Java Math.toRadians() method

The java.lang.Math.toRadians() is a built-in math function in java which is used to convert an angle measured in degrees to an approximately equivalent angle measured in radians.

Syntax

Parameter

Return

If the argument is NaN, this method will return NaN.
If the argument is zero, this method will return zero with the same sign as the argument.
If the argument is infinity, this method will return infinity with the same sign as the argument.

Example 1

public class ToRadiansExample1
{
    public static void main(String[] args) 
    {
        double x = 180.0;
        // converting x from degree to radian
        System.out.println(Math.toRadians(x));
    }
}
