The java.lang.Math.toDegrees() is used to convert an angle measured in radians to an approximately equivalent angle measured in degrees.
Note: The conversion from radians to degrees is generally inexact; users should not expect cos(toRadians(90.0)) to exactly equal 0.0.
public static double toDegrees(double rad) Parameter: rad : This parameter is an angle in radians which we want to convert in degrees. Return : This method returns the measurement of the angle rad in degrees.
Example: To show working of java.lang.Math.toDegrees() method.
180.0 90.0 45.0
