Java - StrictMath toRadians(double x) method

---

---

Description

The Java StrictMath 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.StrictMath.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

Example: Getting Radians for a Positive double Value

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

 package com.tutorialspoint; public class StrictMathDemo { public static void main(String[] args) { // get a double number double x = 45.0; // print the radian for this double System.out.println("StrictMath.toRadians(" + x + ")=" + StrictMath.toRadians(x)); } } 

Output

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

 StrictMath.toRadians(45.0)=0.7853981633974483 

Example: Getting Radians for a Negative double Value

The following example shows the usage of StrictMath toRadians() method to get a radian of a negative double value.

 package com.tutorialspoint; public class StrictMathDemo { public static void main(String[] args) { // get a double number double x = -45.0; // print the radian for this double System.out.println("StrictMath.toRadians(" + x + ")=" + StrictMath.toRadians(x)); } } 

Output

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

 StrictMath.toRadians(-45.0)=-0.7853981633974483 

Example: Getting Radians for a Zero double Value

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

 package com.tutorialspoint; public class StrictMathDemo { public static void main(String[] args) { // get a double number double x = 0.0; // print the radian for this double System.out.println("StrictMath.toRadians(" + x + ")=" + StrictMath.toRadians(x)); } } 

Output

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

 StrictMath.toRadians(0.0)=0.0
