Java - Math toRadians(double x) Method
Description
The Java Math toRadians(double angdeg) converts an angle measured in degrees to an approximately equivalent angle measured in radians. The conversion from degrees to radians is generally inexact.
Declaration
Following is the declaration for java.lang.Math.toRadians() method
public static double toRadians(double angdeg)
Parameters
angdeg − an angle, in degrees
Return Value
This method returns the measurement of the angle angdeg in radians.
Exception
NA
Getting Radians from a Positive Double Value Example
The following example shows the usage of Math toRadians() 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 radian for this double System.out.println("Math.toRadians(" + x + ")=" + Math.toRadians(x)); } }
Output
Let us compile and run the above program, this will produce the following result −
Math.toRadians(45.0)=0.7853981633974483
Getting Radians from a Negative Double Value Example
The following example shows the usage of Math toRadians() method to get a radian 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 radian for this double System.out.println("Math.toRadians(" + x + ")=" + Math.toRadians(x)); } }
Output
Let us compile and run the above program, this will produce the following result −
Math.toRadians(-45.0)=-0.7853981633974483
Getting Radians from a Zero Double Value Example
The following example shows the usage of Math toRadians() 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 radian for this double System.out.println("Math.toRadians(" + x + ")=" + Math.toRadians(x)); } }
Output
Let us compile and run the above program, this will produce the following result −
Math.toRadians(0.0)=0.0
