## NAME

snobol4logic – bitwise logic and conversions for SNOBOL4

## SYNOPSYS

    -INCLUDE 'logic.sno'

## DESCRIPTION

For binary operations, either argument can be INTEGER or STRING (if both string, must be of same length).

NOT(arg)
  returns bitwise not (complement) of integer argument.

AND(arg1,arg2)
  bitwise intersection.

OR(arg1,arg2)
  bitwise union.

XOR(arg1,arg2)
  bitwise exclusive or (equivalence).

NAND(arg1,arg2)
  bitwise intersection (first argument complemented).

NOR(arg1,arg2)
  bitwise union (first argument complemented).

UPLUS(arg1,arg2)
  unsigned addition.

UMINUS(arg1,arg2)
  unsigned subtraction.

UMUL(arg1,arg2)
  unsigned multiplication.

UDIV(arg1,arg2)
  unsigned division.

SHL(arg1,arg2)
  shift left.

SHR(arg1,arg2)
  shift right.

SAR(arg1,arg2)
  arithmetic (signed) shift right.

ROL(arg1,arg2)
  rotate left.

ROR(arg1,arg2)
  rotate right.

HI(str)
  convert base 16 string to integer.

IH(int)
  convert integer to base16 string.

DIB(str,n)
  convert base n string to integer.

IDB(int,n)
  convert integer to base n string.
