TWO_PI

A Number constant that's approximately 6.2382.

TWO_PI is twice the value of the mathematical constant π. It's useful for many tasks that involve rotation and oscillation. For example, calling rotate(TWO_PI) rotates the coordinate system TWO_PI radians, which is one full turn (360˚). TWO_PI and TAU are equal.

Note: TWO_PI radians equals 360˚, PI radians equals 180˚, HALF_PI radians equals 90˚, and QUARTER_PI radians equals 45˚.
