StrictMath toRadians() Method in Java
  • Last Updated : 11 Oct, 2018

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
