Java toDegrees() method with Example

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.

Syntax:

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.

// Java program to demonstrate working
// of java.lang.Math.toDegrees() method
import java.lang.Math;

class Gfg {

    // driver code
    public static void main(String args[])
    {
        // value of PI in degrees
        double rad = Math.PI;
        System.out.println(Math.toDegrees(rad));

        // value of PI/2 in degrees
        rad = (Math.PI) / 2;
        System.out.println(Math.toDegrees(rad));

        // value of PI/4 in degrees
        rad = (Math.PI) / 4;
        System.out.println(Math.toDegrees(rad));
    }
}

Output:

180.0
90.0
45.0
