Uses of Angle in net.grelf

Methods in net.grelf that return Angle

static Angle	Angle.acos(double cos) Inverse cosine.

Angle	Complex.arg() Returns polar angle.
static Angle	Angle.asin(double sin) Inverse sine.
static Angle	Angle.atan(double tan) Inverse tangent.
static Angle	Angle.atan2(double y, double x) Inverse tangent.
Angle	Angle.clone() Returns a new Angle with th same fields.
Angle	Angle.difference(Angle other) Similar to subtract but the result is in the range -180..180 degrees.
