Interface IAngle

All Known Implementing Classes:

Angle, AngleDegrees, AngleRadians

public interface IAngle

This object holds an angle value, and can be used for angle arithmetic (adding, subtracting) and for access to trigonometry functions, such as sine, cosine, tangent. The angle value can be retrieved as degrees or radians.

Nested Class Summary

static class

IAngle.AngleRange An angle object can be set to have values of (-180 to +180] or [0 to +360).
