Eq Float

Note that due to the presence of `NaN`, `Float`'s `Eq` instance does not satisfy reflexivity.

    >>> 0/0 == (0/0 :: Float)
    False

Also note that `Float`'s `Eq` instance does not satisfy extensionality:

    >>> 0 == (-0 :: Float)
    True
    >>> recip 0 == recip (-0 :: Float)
    False

data Char #

The character type `Char` represents Unicode codespace and its elements are code points as in definitions D9 and D10 of the Unicode Standard.

Character literals in Haskell are single-quoted: `'Q'`, `'Я'` or `'Ω'`. To represent a single quote itself use `'\''`, and to represent a backslash use `'\\'`. The full grammar can be found in the section 2.6 of the Haskell 2010 Language Report.

To specify a character by its code point one can use decimal, hexadecimal or octal notation: `'\65'`, `'\x41'` and `'\o101'` are all alternative forms of `'A'`. The largest code point is `'\x10ffff'`.

There is a special escape syntax for ASCII control characters:

Escape | Alternatives | Meaning
--- | --- | ---
`'\NUL'` | `'\0'` | null character
`'\SOH'` | `'\1'` | start of heading
`'\STX'` | `'\2'` | start of text
`'\ETX'` | `'\3'` | end of text
`'\EOT'` | `'\4'` | end of transmission
`'\ENQ'` | `'\5'` | enquiry
`'\ACK'` | `'\6'` | acknowledge
`'\BEL'` | `'\7'`, `'\a'` | bell (alert)
`'\BS'` | `'\8'`, `'\b'` | backspace
`'\HT'` | `'\9'`, `'\t'` | horizontal tab
`'\LF'` | `'\10'`, `'\n'` | line feed (new line)
`'\VT'` | `'\11'`, `'\v'` | vertical tab
`'\FF'` | `'\12'`, `'\f'` | form feed
`'\CR'` | `'\13'`, `'\r'` | carriage return
`'\SO'` | `'\14'` | shift out
`'\SI'` | `'\15'` | shift in
`'\DLE'` | `'\16'` | data link escape
`'\DC1'` | `'\17'` | device control 1
`'\DC2'` | `'\18'` | device control 2
`'\DC3'` | `'\19'` | device control 3
`'\DC4'` | `'\20'` | device control 4
`'\NAK'` | `'\21'` | negative acknowledge
`'\SYN'` | `'\22'` | synchronous idle
`'\ETB'` | `'\23'` | end of transmission block
`'\CAN'` | `'\24'` | cancel
`'\EM'` | `'\25'` | end of medium
`'\SUB'` | `'\26'` | substitute
`'\ESC'` | `'\27'` | escape
`'\FS'` | `'\28'` | file separator
`'\GS'` | `'\29'` | group separator
`'\RS'` | `'\30'` | record separator
`'\US'` | `'\31'` | unit separator
`'\SP'` | `'\32'`, `' '` | space

Data.Char provides utilities to work with `Char`.

data IO a #

A value of type ``IO` a` is a computation which, when performed, does some I/O before returning a value of type `a`.

There is really only one way to "perform" an I/O action: bind it to `Main.main` in your program. When your program is run, the I/O will be performed. It isn't possible to perform I/O from an arbitrary function, unless that function is itself in the `IO` monad and called at some point, directly or indirectly, from `Main.main`.

`IO` is a monad, so `IO` actions can be combined using either the do-notation or the `>>` and `>>=` operations from the `Monad` class.

Eq Double

Note that due to the presence of `NaN`, `Double`'s `Eq` instance does not satisfy reflexivity.

    >>> 0/0 == (0/0 :: Double)
    False

Also note that `Double`'s `Eq` instance does not satisfy substitutivity:

    >>> 0 == (-0 :: Double)
    True
    >>> recip 0 == recip (-0 :: Double)
    False

Instance details Defined in GHC.Classes Methods (==) :: Double -> Double -> Bool # (/=) :: Double -> Double -> Bool #

Ord Double

IEEE 754 `Double`-precision type includes not only numbers, but also positive and negative infinities and a special element called `NaN` (which can be quiet or signal).

IEEE 754-2008, section 5.11 requires that if at least one of arguments of `<=`, `<`, `>`, `>=` is `NaN` then the result of the comparison is `False`, and `instance` `Ord` `Double` complies with this requirement. This violates the reflexivity: both `NaN` `<=` `NaN` and `NaN` `>=` `NaN` are `False`.

IEEE 754-2008, section 5.10 defines `totalOrder` predicate. Unfortunately, `compare` on `Double`s violates the IEEE standard and does not define a total order. More specifically, both `compare` `NaN` `x` and `compare` `x` `NaN` always return `GT`.

Thus, users must be extremely cautious when using `instance` `Ord` `Double`. For instance, one should avoid ordered containers with keys represented by `Double`, because data loss and corruption may happen. An IEEE-compliant `compare` is available in `fp-ieee` package as `TotallyOrdered` newtype.

Moving further, the behaviour of `min` and `max` with regards to `NaN` is also non-compliant. IEEE 754-2008, section 5.3.1 defines that quiet `NaN` should be treated as a missing data by `minNum` and `maxNum` functions, for example, `minNum(NaN, 1) = minNum(1, NaN) = 1`. Some languages such as Java deviate from the standard implementing `minNum(NaN, 1) = minNum(1, NaN) = NaN`. However, `min` / `max` in `base` are even worse: `min` `NaN` 1 is 1, but `min` 1 `NaN` is `NaN`.

IEEE 754-2008 compliant `min` / `max` can be found in `ieee754` package under `minNum` / `maxNum` names. Implementations compliant with `minimumNumber` / `maximumNumber` from a newer IEEE 754-2019, section 9.6 are available from `fp-ieee` package.

class a ~R# b => Coercible (a :: k) (b :: k) #

`Coercible` is a two-parameter class that has instances for types `a` and `b` if the compiler can infer that they have the same representation. This class does not have regular instances; instead they are created on-the-fly during type-checking. Trying to manually declare an instance of `Coercible` is an error.

Nevertheless one can pretend that the following three kinds of instances exist. First, as a trivial base-case:

    instance Coercible a a

Furthermore, for every type constructor there is an instance that allows to coerce under the type constructor. For example, let `D` be a prototypical type constructor (`data` or `newtype`) with three type arguments, which have roles `nominal`, `representational` resp. `phantom`. Then there is an instance of the form

    instance Coercible b b' => Coercible (D a b c) (D a b' c')

Note that the `nominal` type arguments are equal, the `representational` type arguments can differ, but need to have a `Coercible` instance themself, and the `phantom` type arguments can be changed arbitrarily.

The third kind of instance exists for every `newtype NT = MkNT T` and comes in two variants, namely

    instance Coercible a T => Coercible a NT

    instance Coercible T b => Coercible NT b

This instance is only usable if the constructor `MkNT` is in scope.

If, as a library author of a type constructor like `Set a`, you want to prevent a user of your module to write `coerce :: Set T -> Set NT`, you need to set the role of `Set`'s type parameter to `nominal`, by writing

    type role Set nominal

data Integer #

Arbitrary precision integers. In contrast with fixed-size integral types such as `Int`, the `Integer` type represents the entire infinite range of integers.

Integers are stored in a kind of sign-magnitude form, hence do not expect two's complement form when using bit operations.

If the value is small (i.e., fits into an `Int`), the `IS` constructor is used. Otherwise `IP` and `IN` constructors are used to store a `BigNat` representing the positive or the negative value magnitude, respectively.

Invariant: `IP` and `IN` are used iff the value does not fit in `IS`.

type Type = TYPE LiftedRep #

The kind of types with lifted values. For example `Int :: Type`.

type Constraint = CONSTRAINT LiftedRep #

The kind of lifted constraints

(++) :: [a] -> [a] -> [a] infixr 5 #

`(++)` appends two lists, i.e.,

    [x1, ..., xm] ++ [y1, ..., yn] == [x1, ..., xm, y1, ..., yn]
    [x1, ..., xm] ++ [y1, ...] == [x1, ..., xm, y1, ...]

If the first list is not finite, the result is the first list.

#### Performance considerations

Expand

This function takes linear time in the number of elements of the first list. Thus it is better to associate repeated applications of `(++)` to the right (which is the default behaviour): `xs ++ (ys ++ zs)` or simply `xs ++ ys ++ zs`, but not `(xs ++ ys) ++ zs`. For the same reason `concat` `=` `foldr` `(++)` `[]` has linear performance, while `foldl` `(++)` `[]` is prone to quadratic slowdown

#### Examples

Expand

    >>> [1, 2, 3] ++ [4, 5, 6]
    [1,2,3,4,5,6]

    >>> [] ++ [1, 2, 3]
    [1,2,3]

    >>> [3, 2, 1] ++ []
    [3,2,1]

seq :: a -> b -> b infixr 0 #

The value of ``seq` a b` is bottom if `a` is bottom, and otherwise equal to `b`. In other words, it evaluates the first argument `a` to weak head normal form (WHNF). `seq` is usually introduced to improve performance by avoiding unneeded laziness.

A note on evaluation order: the expression ``seq` a b` does not guarantee that `a` will be evaluated before `b`. The only guarantee given by `seq` is that the both `a` and `b` will be evaluated before `seq` returns a value. In particular, this means that `b` may be evaluated before `a`. If you need to guarantee a specific order of evaluation, you must use the function `pseq` from the "parallel" package.

print :: Show a => a -> IO () #

The `print` function outputs a value of any printable type to the standard output device. Printable types are those that are instances of class `Show`; `print` converts values to strings for output using the `show` operation and adds a newline.

For example, a program to print the first 20 integers and their powers of 2 could be written as:

    main = print ([(n, 2^n) | n <- [0..19]])

class Num a where #

Basic numeric class.

The Haskell Report defines no laws for `Num`. However, `(`+`)` and `(`*`)` are customarily expected to define a ring and have the following properties:

Associativity of `(`+`)`
  `(x + y) + z` = `x + (y + z)`
Commutativity of `(`+`)`
  `x + y` = `y + x`
``fromInteger` 0` is the additive identity
  `x + fromInteger 0` = `x`
`negate` gives the additive inverse
  `x + negate x` = `fromInteger 0`
Associativity of `(`*`)`
  `(x * y) * z` = `x * (y * z)`
``fromInteger` 1` is the multiplicative identity
  `x * fromInteger 1` = `x` and `fromInteger 1 * x` = `x`
Distributivity of `(`*`)` with respect to `(`+`)`
  `a * (b + c)` = `(a * b) + (a * c)` and `(b + c) * a` = `(b * a) + (c * a)`
Coherence with `toInteger`
  if the type also implements `Integral`, then `fromInteger` is a left inverse for `toInteger`, i.e. `fromInteger (toInteger i) == i`

Note that it isn't customarily expected that a type instance of both `Num` and `Ord` implement an ordered ring. Indeed, in `base` only `Integer` and `Rational` do.

Minimal complete definition

(+), (*), abs, signum, fromInteger, (negate | (-))

Methods

(+) :: a -> a -> a infixl 6 #

(-) :: a -> a -> a infixl 6 #

(*) :: a -> a -> a infixl 7 #

negate :: a -> a #

Unary negation.

abs :: a -> a #

Absolute value.

signum :: a -> a #

Sign of a number. The functions `abs` and `signum` should satisfy the law:

    abs x * signum x == x

For real numbers, the `signum` is either `-1` (negative), `0` (zero) or `1` (positive).

fromInteger :: Integer -> a #

Conversion from an `Integer`. An integer literal represents the application of the function `fromInteger` to the appropriate value of type `Integer`, so such literals have type `(`Num` a) => a`.

(Applicative f, Num a) => Num (Ap f a)

Note that even if the underlying `Num` and `Applicative` instances are lawful, for most `Applicative`s, this instance will not be lawful. If you use this instance with the list `Applicative`, the following customary laws will not hold:

Commutativity:

    >>> Ap [10,20] + Ap [1,2]
    Ap {getAp = [11,12,21,22]}
    >>> Ap [1,2] + Ap [10,20]
    Ap {getAp = [11,21,12,22]}

Additive inverse:

    >>> Ap [] + negate (Ap [])
    Ap {getAp = []}
    >>> fromInteger 0 :: Ap [] Int
    Ap {getAp = [0]}

Distributivity:

    >>> Ap [1,2] * (3 + 4)
    Ap {getAp = [7,14]}
    >>> (Ap [1,2] * 3) + (Ap [1,2] * 4)

class Num a => Fractional a where #

Fractional numbers, supporting real division.

The Haskell Report defines no laws for `Fractional`. However, `(`+`)` and `(`*`)` are customarily expected to define a division ring and have the following properties:

`recip` gives the multiplicative inverse
  `x * recip x` = `recip x * x` = `fromInteger 1`
Totality of `toRational`
  `toRational` is total
Coherence with `toRational`
  if the type also implements `Real`, then `fromRational` is a left inverse for `toRational`, i.e. `fromRational (toRational i) = i`

Note that it isn't customarily expected that a type instance of `Fractional` implement a field. However, all instances in `base` do.

Minimal complete definition

fromRational, (recip | (/))

Methods

(/) :: a -> a -> a infixl 7 #

Fractional division.

recip :: a -> a #

Reciprocal fraction.

fromRational :: Rational -> a #

Conversion from a `Rational` (that is ``Ratio` `Integer``). A floating literal stands for an application of `fromRational` to a value of type `Rational`, so such literals have type `(`Fractional` a) => a`.

class Enum a where #

Class `Enum` defines operations on sequentially ordered types.

The `enumFrom`... methods are used in Haskell's translation of arithmetic sequences.

Instances of `Enum` may be derived for any enumeration type (types whose constructors have no fields). The nullary constructors are assumed to be numbered left-to-right by `fromEnum` from `0` through `n-1`. See Chapter 10 of the Haskell Report for more details.

For any type that is an instance of class `Bounded` as well as `Enum`, the following should hold:

- The calls ``succ` `maxBound`` and ``pred` `minBound`` should result in a runtime error.
- `fromEnum` and `toEnum` should give a runtime error if the result value is not representable in the result type. For example, ``toEnum` 7 :: `Bool`` is an error.
- `enumFrom` and `enumFromThen` should be defined with an implicit bound, thus:

       enumFrom     x   = enumFromTo     x maxBound
       enumFromThen x y = enumFromThenTo x y bound
         where
           bound | fromEnum y >= fromEnum x = maxBound
                 | otherwise                = minBound

Minimal complete definition

toEnum, fromEnum

Methods

succ :: a -> a #

Successor of a value. For numeric types, `succ` adds 1.

pred :: a -> a #

Predecessor of a value. For numeric types, `pred` subtracts 1.

toEnum :: Int -> a #

Convert from an `Int`.

fromEnum :: a -> Int #

Convert to an `Int`. It is implementation-dependent what `fromEnum` returns when applied to a value that is too large to fit in an `Int`.

enumFrom :: a -> [a] #

Used in Haskell's translation of `[n..]` with `[n..] = enumFrom n`, a possible implementation being `enumFrom n = n : enumFrom (succ n)`.

#### Examples

Expand

-     enumFrom 4 :: [Integer] = [4,5,6,7,...]

-     enumFrom 6 :: [Int] = [6,7,8,9,...,maxBound :: Int]

enumFromThen :: a -> a -> [a] #

Used in Haskell's translation of `[n,n'..]` with `[n,n'..] = enumFromThen n n'`, a possible implementation being `enumFromThen n n' = n : n' : worker (f x) (f x n')`, `worker s v = v : worker s (s v)`, `x = fromEnum n' - fromEnum n` and

      f n y
        | n > 0 = f (n - 1) (succ y)
        | n < 0 = f (n + 1) (pred y)
        | otherwise = y

#### Examples

Expand

-     enumFromThen 4 6 :: [Integer] = [4,6,8,10...]

-     enumFromThen 6 2 :: [Int] = [6,2,-2,-6,...,minBound :: Int]

enumFromTo :: a -> a -> [a] #

Used in Haskell's translation of `[n..m]` with `[n..m] = enumFromTo n m`, a possible implementation being

      enumFromTo n m
         | n <= m = n : enumFromTo (succ n) m
         | otherwise = []

#### Examples

Expand

-     enumFromTo 6 10 :: [Int] = [6,7,8,9,10]

-     enumFromTo 42 1 :: [Integer] = []

enumFromThenTo :: a -> a -> a -> [a] #

Used in Haskell's translation of `[n,n'..m]` with `[n,n'..m] = enumFromThenTo n n' m`, a possible implementation being `enumFromThenTo n n' m = worker (f x) (c x) n m`, `x = fromEnum n' - fromEnum n`, `c x = bool (>=) ((x 0)`

      f n y
         | n > 0 = f (n - 1) (succ y)
         | n < 0 = f (n + 1) (pred y)
         | otherwise = y

and

      worker s c v m
         | c v m = v : worker s c (s v) m
         | otherwise = []

Enum (Fixed a)

Recall that, for numeric types, `succ` and `pred` typically add and subtract `1`, respectively. This is not true in the case of `Fixed`, whose successor and predecessor functions intuitively return the "next" and "previous" values in the enumeration. The results of these functions thus depend on the resolution of the `Fixed` value. For example, when enumerating values of resolution `10^-3` of `type Milli = Fixed E3`,

    >>> succ (0.000 :: Milli)
    0.001

and likewise

    >>> pred (0.000 :: Milli)
    -0.001

In other words, `succ` and `pred` increment and decrement a fixed-precision value by the least amount such that the value's resolution is unchanged. For example, `10^-12` is the smallest (positive) amount that can be added to a value of `type Pico = Fixed E12` without changing its resolution, and so

    >>> succ (0.000000000000 :: Pico)
    0.000000000001

and similarly

    >>> pred (0.000000000000 :: Pico)
    -0.000000000001

This is worth bearing in mind when defining `Fixed` arithmetic sequences. In particular, you may be forgiven for thinking the sequence

      [1..10] :: [Pico]

evaluates to `[1, 2, 3, 4, 5, 6, 7, 8, 9, 10] :: [Pico]`.

However, this is not true. On the contrary, similarly to the above implementations of `succ` and `pred`, `enumFromTo :: Pico -> Pico -> [Pico]` has a "step size" of `10^-12`. Hence, the list `[1..10] :: [Pico]` has the form

      [1.000000000000, 1.00000000001, 1.00000000002, ..., 10.000000000000]

and contains `9 * 10^12 + 1` values.

class (Real a, Enum a) => Integral a where #

Integral numbers, supporting integer division.

The Haskell Report defines no laws for `Integral`. However, `Integral` instances are customarily expected to define a Euclidean domain and have the following properties for the `div`/`mod` and `quot`/`rem` pairs, given suitable Euclidean functions `f` and `g`:

- `x` = `y * quot x y + rem x y` with `rem x y` = `fromInteger 0` or `g (rem x y)` < `g y`
- `x` = `y * div x y + mod x y` with `mod x y` = `fromInteger 0` or `f (mod x y)` < `f y`

An example of a suitable Euclidean function, for `Integer`'s instance, is `abs`.

In addition, `toInteger` should be total, and `fromInteger` should be a left inverse for it, i.e. `fromInteger (toInteger i) = i`.

The Haskell report defines no laws for `Real`, however `Real` instances are customarily expected to adhere to the following law:

Coherence with `fromRational`
  if the type also implements `Fractional`, then `fromRational` is a left inverse for `toRational`, i.e. `fromRational (toRational i) = i`

The law does not hold for `Float`, `Double`, `CFloat`, `CDouble`, etc., because these types contain non-finite values, which cannot be roundtripped through `Rational`.

Methods

toRational :: a -> Rational #

Rational equivalent of its real argument with full precision.

class Bounded a where #

The `Bounded` class is used to name the upper and lower limits of a type. `Ord` is not a superclass of `Bounded` since types that are not totally ordered may also have upper and lower bounds.

The `Bounded` class may be derived for any enumeration type; `minBound` is the first constructor listed in the `data` declaration and `maxBound` is the last. `Bounded` may also be derived for single-constructor datatypes whose constituent types are in `Bounded`.

class Fractional a => Floating a where #

Trigonometric and hyperbolic functions and related functions.

The Haskell Report defines no laws for `Floating`. However, `(`+`)`, `(`*`)` and `exp` are customarily expected to define an exponential field and have the following properties:

- `exp (a + b)` = `exp a * exp b`
- `exp (fromInteger 0)` = `fromInteger 1`

expm1 :: a -> a #

``expm1` x` computes ``exp` x - 1`, but provides more precise results for small (absolute) values of `x` if possible.

@since base-4.9.0.0

log1pexp :: a -> a #

``log1pexp` x` computes ``log` (1 + `exp` x)`, but provides more precise results if possible.

Examples:

- if `x` is a large negative number, ``log` (1 + `exp` x)` will be imprecise for the reasons given in `log1p`.
- if ``exp` x` is close to `-1`, ``log` (1 + `exp` x)` will be imprecise for the reasons given in `expm1`.

log1mexp :: a -> a #

``log1mexp` x` computes ``log` (1 - `exp` x)`, but provides more precise results if possible.

Examples:

- if `x` is a large negative number, ``log` (1 - `exp` x)` will be imprecise for the reasons given in `log1p`.
- if ``exp` x` is close to `1`, ``log` (1 - `exp` x)` will be imprecise for the reasons given in `expm1`.

Minimal complete definition

floatRadix, floatDigits, floatRange, decodeFloat, encodeFloat, isNaN, isInfinite, isDenormalized, isNegativeZero, isIEEE

Methods

floatRadix :: a -> Integer #

a constant function, returning the radix of the representation (often `2`)

floatDigits :: a -> Int #

a constant function, returning the number of digits of `floatRadix` in the significand

floatRange :: a -> (Int, Int) #

a constant function, returning the lowest and highest values the exponent may assume

decodeFloat :: a -> (Integer, Int) #

The function `decodeFloat` applied to a real floating-point number returns the significand expressed as an `Integer` and an appropriately scaled exponent (an `Int`). If ``decodeFloat` x` yields `(m,n)`, then `x` is equal in value to `m*b^^n`, where `b` is the floating-point radix, and furthermore, either `m` and `n` are both zero or else `b^(d-1) <= `abs` m < b^d`, where `d` is the value of ``floatDigits` x`. In particular, ``decodeFloat` 0 = (0,0)`. If the type contains a negative zero, also ``decodeFloat` (-0.0) = (0,0)`. The result of ``decodeFloat` x` is unspecified if either of ``isNaN` x` or ``isInfinite` x` is `True`.

encodeFloat :: Integer -> Int -> a #

`encodeFloat` performs the inverse of `decodeFloat` in the sense that for finite `x` with the exception of `-0.0`, ``uncurry` `encodeFloat` (`decodeFloat` x) = x`. ``encodeFloat` m n` is one of the two closest representable floating-point numbers to `m*b^^n` (or `±Infinity` if overflow occurs); usually the closer, but if `m` contains too many bits, the result may be rounded in the wrong direction.

exponent :: a -> Int #

`exponent` corresponds to the second component of `decodeFloat`. ``exponent` 0 = 0` and for finite nonzero `x`, ``exponent` x = snd (`decodeFloat` x) + `floatDigits` x`. If `x` is a finite floating-point number, it is equal in value to ``significand` x * b ^^ `exponent` x`, where `b` is the floating-point radix. The behaviour is unspecified on infinite or `NaN` values.

significand :: a -> a #

The first component of `decodeFloat`, scaled to lie in the open interval (`-1`,`1`), either `0.0` or of absolute value `>= 1/b`, where `b` is the floating-point radix. The behaviour is unspecified on infinite or `NaN` values.

scaleFloat :: Int -> a -> a #

multiplies a floating-point number by an integer power of the radix

isNaN :: a -> Bool #

`True` if the argument is an IEEE "not-a-number" (NaN) value

isInfinite :: a -> Bool #

`True` if the argument is an IEEE infinity or negative infinity

isDenormalized :: a -> Bool #

`True` if the argument is too small to be represented in normalized format

isNegativeZero :: a -> Bool #

`True` if the argument is an IEEE negative zero

isIEEE :: a -> Bool #

`True` if the argument is an IEEE floating point number

atan2 :: a -> a -> a #

a version of arctangent taking two real floating-point arguments. For real floating `x` and `y`, ``atan2` y x` computes the angle (from the positive x-axis) of the vector from the origin to the point `(x,y)`. ``atan2` y x` returns a value in the range [`-pi`, `pi`]. It follows the Common Lisp semantics for the origin when signed zeroes are supported. ``atan2` y 1`, with `y` in a type that is `RealFloat`, should return the same value as ``atan` y`. A default definition of `atan2` is provided, but implementors can provide a more accurate implementation.

properFraction

Methods

properFraction :: Integral b => a -> (b, a) #

The function `properFraction` takes a real fractional number `x` and returns a pair `(n,f)` such that `x = n+f`, and:

- `n` is an integral number with the same sign as `x`; and
- `f` is a fraction with the same type and sign as `x`, and with absolute value less than `1`.

The default definitions of the `ceiling`, `floor`, `truncate` and `round` functions are in terms of `properFraction`.

truncate :: Integral b => a -> b #

``truncate` x` returns the integer nearest `x` between zero and `x`

round :: Integral b => a -> b #

``round` x` returns the nearest integer to `x`; the even integer if `x` is equidistant between two integers

ceiling :: Integral b => a -> b #

``ceiling` x` returns the least integer not less than `x`

floor :: Integral b => a -> b #

``floor` x` returns the greatest integer not greater than `x`

class Show a where #

Conversion of values to readable `String`s.

Derived instances of `Show` have the following properties, which are compatible with derived instances of `Read`:

- The result of `show` is a syntactically correct Haskell expression containing only constants, given the fixity declarations in force at the point where the type is declared. It contains only the constructor names defined in the data type, parentheses, and spaces. When labelled constructor fields are used, braces, commas, field names, and equal signs are also used.
- If the constructor is defined to be an infix operator, then `showsPrec` will produce infix applications of the constructor.
- the representation will be enclosed in parentheses if the precedence of the top-level constructor in `x` is less than `d` (associativity is ignored). Thus, if `d` is `0` then the result is never surrounded in parentheses; if `d` is `11` it is always surrounded in parentheses, unless it is an atomic expression.
- If the constructor is defined using record syntax, then `show` will produce the record-syntax form, with the fields given in the same order as the original declaration.

For example, given the declarations

    infixr 5 :^:
    data Tree a =  Leaf a  |  Tree a :^: Tree a

the derived instance of `Show` is equivalent to

    instance (Show a) => Show (Tree a) where

           showsPrec d (Leaf m) = showParen (d > app_prec) $
                showString "Leaf " . showsPrec (app_prec+1) m
             where app_prec = 10

           showsPrec d (u :^: v) = showParen (d > up_prec) $
                showsPrec (up_prec+1) u .
                showString " :^: "      .
                showsPrec (up_prec+1) v
             where up_prec = 5

Note that right-associativity of `:^:` is ignored. For example,

- ``show` (Leaf 1 :^: Leaf 2 :^: Leaf 3)` produces the string `"Leaf 1 :^: (Leaf 2 :^: Leaf 3)"`.

showsPrec | show

Methods

showsPrec #

Arguments

:: Int | the operator precedence of the enclosing context (a number from `0` to `11`). Function application has precedence `10`.
-> a | the value to be converted to a `String`
-> ShowS |

Convert a value to a readable `String`.

`showsPrec` should satisfy the law

    showsPrec d x r ++ s  ==  showsPrec d x (r ++ s)

Derived instances of `Read` and `Show` satisfy the following:

- `(x,"")` is an element of `(`readsPrec` d (`showsPrec` d x ""))`.

That is, `readsPrec` parses the string produced by `showsPrec`, and delivers the value that `showsPrec` started with.

show :: a -> String #

A specialised variant of `showsPrec`, using precedence context zero, and returning an ordinary `String`.

showList :: [a] -> ShowS #

The method `showList` is provided to allow the programmer to give a specialised way of showing lists of values. For example, this is used by the predefined `Show` instance of the `Char` type, where values of type `String` should be shown in double quotes, rather than between square brackets.

data Ratio a #

Rational numbers, with numerator and denominator of some `Integral` type.

Note that `Ratio`'s instances inherit the deficiencies from the type parameter's. For example, `Ratio Natural`'s `Num` instance has similar problems to `Natural`'s.

type Rational = Ratio Integer #

Arbitrary-precision rational numbers, represented as a ratio of two `Integer` values. A rational number may be constructed using the `%` operator.

data Ptr a #

A value of type ``Ptr` a` represents a pointer to an object, or an array of objects, which may be marshalled to or from Haskell values of type `a`.

The type `a` will often be an instance of class `Storable` which provides the marshalling operations. However this is not essential, and you can provide your own operations to access the pointer. For example you might write small foreign functions to get or set the fields of a C `struct`.

data FunPtr a #

A value of type ``FunPtr` a` is a pointer to a function callable from foreign code. The type `a` will normally be a foreign type, a function type with zero or more arguments where

- the argument types are marshallable foreign types, i.e. `Char`, `Int`, `Double`, `Float`, `Bool`, `Int8`, `Int16`, `Int32`, `Int64`, `Word8`, `Word16`, `Word32`, `Word64`, ``Ptr` a`, ``FunPtr` a`, ``StablePtr` a` or a renaming of any of these using `newtype`.
- the return type is either a marshallable foreign type or has the form ``IO` t` where `t` is a marshallable foreign type or `()`.

A value of type ``FunPtr` a` may be a pointer to a foreign function, either returned by another foreign function or imported with a a static address import like

    foreign import ccall "stdlib.h &free"
      p_free :: FunPtr (Ptr a -> IO ())

or a pointer to a Haskell function created using a wrapper stub declared to produce a `FunPtr` of the correct type. For example:

    type Compare = Int -> Int -> Bool
    foreign import ccall "wrapper"
      mkCompare :: Compare -> IO (FunPtr Compare)

Calls to wrapper stubs like `mkCompare` allocate storage, which should be released with `freeHaskellFunPtr` when no longer required.

To convert `FunPtr` values to corresponding Haskell functions, one can define a dynamic stub for the specific foreign type, e.g.

    type IntFunction = CInt -> IO ()
    foreign import ccall "dynamic"
      mkFun :: FunPtr IntFunction -> IntFunction

data CallStack #

`CallStack`s are a lightweight method of obtaining a partial call-stack at any point in the program.

A function can request its call-site with the `HasCallStack` constraint. For example, we can define

    putStrLnWithCallStack :: HasCallStack => String -> IO ()

as a variant of `putStrLn` that will get its call-site and print it, along with the string given as argument. We can access the call-stack inside `putStrLnWithCallStack` with `callStack`.

    >>> :{
    putStrLnWithCallStack :: HasCallStack => String -> IO ()
    putStrLnWithCallStack msg = do
      putStrLn msg
      putStrLn (prettyCallStack callStack)
    :}

Thus, if we call `putStrLnWithCallStack` we will get a formatted call-stack alongside our string.

    >>> putStrLnWithCallStack "hello"
    hello
    CallStack (from HasCallStack):
      putStrLnWithCallStack, called at <interactive>:... in interactive:Ghci...

GHC solves `HasCallStack` constraints in three steps:

1. If there is a `CallStack` in scope -- i.e. the enclosing function has a `HasCallStack` constraint -- GHC will append the new call-site to the existing `CallStack`.
2. If there is no `CallStack` in scope -- e.g. in the GHCi session above -- and the enclosing definition does not have an explicit type signature, GHC will infer a `HasCallStack` constraint for the enclosing definition (subject to the monomorphism restriction).
3. If there is no `CallStack` in scope and the enclosing definition has an explicit type signature, GHC will solve the `HasCallStack` constraint for the singleton `CallStack` containing just the current call-site.

`CallStack`s do not interact with the RTS and do not require compilation with `-prof`. On the other hand, as they are built up explicitly via the `HasCallStack` constraints, they will generally not contain as much information as the simulated call-stacks maintained by the RTS.

A `CallStack` is a `[(String, SrcLoc)]`. The `String` is the name of function that was called, the `SrcLoc` is the call-site. The list is ordered with the most recently called function at the head.

NOTE: The intrepid user may notice that `HasCallStack` is just an alias for an implicit parameter `?callStack :: CallStack`. This is an implementation detail and should not be considered part of the `CallStack` API, we may decide to change the implementation in the future.

ord :: Char -> Int #

The `fromEnum` method restricted to the type `Char`.

minInt :: Int #

maxInt :: Int #

until :: (a -> Bool) -> (a -> a) -> a -> a #

``until` p f` yields the result of applying `f` until `p` holds.

asTypeOf :: a -> a -> a #

`asTypeOf` is a type-restricted version of `const`. It is usually used as an infix operator, and its typing forces its first argument (which is usually overloaded) to have the same type as the second.

currentCallStack :: IO [String] #

Returns a `[String]` representing the current call stack. This can be useful for debugging.

The implementation uses the call-stack simulation maintained by the profiler, so it only works if the program was compiled with `-prof` and contains suitable SCC annotations (e.g. by using `-fprof-auto`). Otherwise, the list returned is likely to be empty or uninformative.

-> Int | the precedence of the enclosing context
-> a | the value to show
-> ShowS |

Converts a possibly-negative `Real` value to a string.

(^^%^^) :: Integral a => Rational -> a -> Rational #

gcd :: Integral a => a -> a -> a #

``gcd` x y` is the non-negative factor of both `x` and `y` of which every common factor of `x` and `y` is also a factor; for example ``gcd` 4 2 = 2`, ``gcd` (-4) 6 = 2`, ``gcd` 0 4` = `4`. ``gcd` 0 0` = `0`. (That is, the common divisor that is "greatest" in the divisibility preordering.)

Note: Since for signed fixed-width integer types, ``abs` `minBound` < 0`, the result may be negative if one of the arguments is ``minBound`` (and necessarily is if the other is `0` or ``minBound``) for such types.
