Easy way to keeping angles between -179 and 180 degrees

Question

Is there an easy way to convert an angle (in degrees) to be between -179 and 180? I\'m sure I could use mod (%) and some if statements, but it gets ugly:

/         


        

Answer 1

It is better to use library functions. They handle special cases like NaN and infinities.

public static double normalizeAngleDegrees(double angle) {
    return Math.toDegrees(Math.atan2(Math.sin(Math.toRadians(angle)), Math.cos(Math.toRadians(angle))));
}
