Java - Math toDegrees(double x) method

---

---

Description

The Java 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 1

The following example shows the usage of Math toDegrees() method for a positive double value.

package com.tutorialspoint;
public class MathDemo {
   public static void main(String[] args) {

      // get a double number
      double x = 45.0;

      // print the degree for this double
      System.out.println("Math.toDegrees(" + x + ")=" + Math.toDegrees(x));
   }
}

Output

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

Math.toDegrees(45.0)=2578.3100780887044

Example 2

The following example shows the usage of Math toDegrees() method to get a degree of a negative double value.

package com.tutorialspoint;
public class MathDemo {
   public static void main(String[] args) {

      // get a double number
      double x = -45.0;

      // print the degree for this double
      System.out.println("Math.toDegrees(" + x + ")=" + Math.toDegrees(x));
   }
}

Output

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

Math.toDegrees(-45.0)=-2578.3100780887044

Example 3

The following example shows the usage of Math toDegrees() method to get a value of a zero double values.

package com.tutorialspoint;
public class MathDemo {
   public static void main(String[] args) {

      // get a double number
      double x = 0.0;

      // print the degree for this double
      System.out.println("Math.toDegrees(" + x + ")=" + Math.toDegrees(x));
   }
}

Output

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

Math.toDegrees(0.0)=0.0
