Angle utils

A small and compact utility library for dealing with all kinds of angles. This library supports radians, degrees, turns and gradians.

Angle

var angle = Angle.degrees(90);
angle.radians;  // pi/2
angle.degrees;  // 90
angle.gradians; // 100
angle.turns;    // 1/4

var full = Angle.full();
full.radians;   // 2*pi
full.degrees;   // 360
full.gradians;  // 400
full.turns;     // 1

var diff = full - angle;
diff.degrees; // 270

var other = Angle.degrees(-10);
other.normalized.degrees; // 350

AngleRange

This library also provides an AngleRange type:

var range = AngleRange(start: Angle.degrees(80), end: Angle.degrees(100));
range.start;    // Angle.degrees(80)
range.end;      // Angle.degrees(100)
range.mid;      // Angle.degrees(90)
range.sweep;    // Angle.degrees(20)

range.includes(Angle.degrees(90)); // true
range.includes(Angle.degrees(70)); // false
