Uses of Angle in net.grelf

Methods in net.grelf that return Angle

Modifier and Type	Method and Description
static Angle	Angle.acos(double cos) Inverse cosine.
Angle	Angle.add(Angle other) Returns new Angle which is the sum of the present one and other.
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 the same fields.
Angle	Angle.difference(Angle other) Similar to subtract but the result is in the range -180..180 degrees.
Angle	Angle.in360() Returns a new Angle whose value lies in range 0..360 degrees (or 0..2pi radians).
Angle	Angle.multiply(double factor) Returns a new Angle that is the result of multiplying the current one by a factor.
static Angle	Angle.parseAngle(java.lang.String s) Allow all possible formatting of the String.
Angle	Angle.subtract(Angle other) Returns a new Angle which is the result of subtracting other from this.

Methods in net.grelf with parameters of type Angle

Modifier and Type	Method and Description
Angle	Angle.add(Angle other) Returns new Angle which is the sum of the present one and other.
static Maths.Statistics	Angle.angleStatistics(Angle... angles) Calculate the min, max, mean and stdDev (all in degrees) of an array of angles, taking into account periodicity.
int	Angle.compareTo(Angle other) Implements java.lang.Comparable
Angle	Angle.difference(Angle other) Similar to subtract but the result is in the range -180..180 degrees.
boolean	Triangle.equalAngles(Triangle other, Angle tolerance) True even if the vertices are cycled round in the other triangle, in which case - NB! - other is cycled by this method so it matches, but false if other is flipped over relative to this.
boolean	Angle.equals(Angle other, Angle tolerance)
static Complex	Complex.expi(Angle theta) Get exp (i.theta) = cos (theta) + i.sin (theta).
Angle	Angle.subtract(Angle other) Returns a new Angle which is the result of subtracting other from this.
