Java toRadians() method with Example

The java.lang.Math.toRadians() is used to convert an angle measured in degrees to an approximately equivalent angle measured in radians.

Note: The conversion from degrees to radian is generally inexact.

Syntax:

public static double toRadians(double deg)

Parameter:
deg : This parameter is an angle in degrees which
we want to convert in radians.
Return :
This method returns the measurement of the angle 
deg in radians.

Example: To show working of java.lang.Math.toRadians() method.

// Java program to demonstrate working 
// of java.lang.Math.toRadians() method 
import java.lang.Math; 
  
class Gfg { 
  
    // driver code 
    public static void main(String args[]) 
    { 
        // convertng PI from degree to radian 
        double deg = 180.0; 
        System.out.println(Math.toRadians(deg)); 
  
        // convertng PI/2 from degree to radian 
        deg = 90.0; 
        System.out.println(Math.toRadians(deg)); 
  
        // convertng PI/4 from degree to radian 
        deg = 45.0; 
        System.out.println(Math.toRadians(deg)); 
    } 
} 

Output:

3.141592653589793
1.5707963267948966
0.7853981633974483
