Never ever suffix your angle variables with ...degress or ...rad and forget about manual angle conversions like x * rad2deg!

This library provides a single class named Angle, wrapping your angle variables in a far more readable way, whereas raw doubles aren't very expressive about how they store their values. One can create an angle from various units, including degrees, radians, gradians and turns.

// Various ways to define a half turn:
x = Angle.fromDegrees(180.0);
y = Angle.fromRadians(math.pi);
z = Angle.fromTurns(0.5);

x.degrees; // = 180.0
x.radians; // = 3.1415...
x.turns;   // = 0.5

One can use built-in trigonometric functions:

x = Angle.asin(0.3);
y = x.sin; // = 0.3

Angles are immutable, but there are operators like +, creating new angles:

x = Angle.halfTurn() + Angle.fromDegrees(90.0);


Support for angles in a more readable way than raw doubles. Never every about the unit your angle is stored in.
