The java.lang.StrictMath.toRadians() method of StrictMath class in Java is used to accept an angle measured in degrees as a parameter and returns its approximately equivalent angle measured in radians. So basically it converts degree to radians. This conversion is generally inexact.
Syntax:
public static double toRadians(double deg)
Parameters: This function accepts a single parameter deg which refers to an angle in degrees which is to be converted to its equivalent radians.
Return Values: This method returns the measurement of the angle passed as a parameter, in radians.
Examples:
Input : 120 Output : 2.0943951023931953 Input : 0.00087104 Output : 1.5202515916571408E-5
Below programs illustrate the java.lang.StrictMath.toRadians() method in Java :
Program 1:
// Java Program to illustrate // StrictMath.toRadians() function   import java.io.*;import java.lang.*;  class GFG {    public static void main(String[] args)    {          double deg = 108.478;        double rad = StrictMath.toRadians(deg);        System.out.println("Value in radian of " +                      deg + " degrees is " + rad);    }} |
Output:
Value in radian of 108.478 degrees is 1.8932982659784086
Program 2:
// Java Program to illustrate StrictMath.toRadians()// function   import java.io.*;import java.lang.*;  class GFG {    public static void main(String[] args)    {          double deg = 360.0;        double rad = StrictMath.toRadians(deg);        System.out.println("Value in radian of " +                      deg + " degrees is " + rad);    }} |
Output:
Value in radian of 360.0 degrees is 6.283185307179586
