All Implemented Interfaces:

java.io.Serializable, CountConvertible, RealConvertible, Code, Theable

public class MathToDegrees
extends AbstractMath
implements Theable, RealConvertible, CountConvertible

Math. Converts an angle measured in radians to an approximately equivalent angle measured in degrees.

Example

 \the\mathtodegrees 0.234
 \real7=\mathtodegrees 0.56
 \real8=\mathtodegrees\real7
 \count99=\mathtodegrees 1.34
