Java.lang.Math.toDegrees() Method

---

Description

The java.lang.Math.toDegrees(double angrad) converts an angle measured in radians to an approximately equivalent angle measured in degrees. The conversion from radians to degrees is generally inexact; users should not expect cos(toRadians(90.0)) to exactly equal 0.0.

Declaration

Following is the declaration for java.lang.Math.toDegrees() method

public static double toDegrees(double angrad)

Parameters

angrad − an angle, in radians

Return Value

This method returns the measurement of the angle angrad in degrees.

Exception

NA

Example

The following example shows the usage of lang.Math.toDegrees() method.

package com.tutorialspoint;

import java.lang.*;

public class MathDemo {

   public static void main(String[] args) {

      // get two double numbers numbers
      double x = 45;
      double y = -180;

      // convert them in degrees
      x = Math.toDegrees(x);
      y = Math.toDegrees(y);

      // print the hyperbolic tangent of these doubles
      System.out.println("Math.tanh(" + x + ")=" + Math.tanh(x));
      System.out.println("Math.tanh(" + y + ")=" + Math.tanh(y));
   }
}

Let us compile and run the above program, this will produce the following result −

Math.tanh(2578.3100780887044)=1.0
Math.tanh(-10313.240312354817)=-1.0
