## Detailed Description

A double that's an angle.

An Angle is really nothing more than a double. Having a separate type is sometimes useful, for instance in the Vector constructor, and this class serves as the right place for a few utility functions. It also makes it clear whether a value is in radians or in degrees.

## Constructor & Destructor Documentation

ipe::Angle::Angle | ( |  | ) | `[inline, explicit]`

Construct uninitialized angle.

ipe::Angle::Angle | ( | double | alpha | ) | `[inline]`

Construct an angle (in radians).

## Member Function Documentation

static Angle ipe::Angle::Degrees | ( | double | alpha | ) | `[inline, static]`

Construct an angle in degrees.

ipe::Angle::operator double | ( |  | ) | const`[inline]`

Return value (in radians).

double Angle::degrees | ( |  | ) | const

Angle Angle::normalize | ( | double | lowlimit | ) |

Normalize the value to the range lowlimit .. lowlimit + 2 pi.

This Angle object is modified, a copy is returned.

bool Angle::liesBetween | ( | Angle | small,
|  | Angle | large
| ) |  | const

When considering the positively oriented circle arc from angle small to large, does it cover this angle?
