Java Math toRadians() Method

The toRadians() method of Java Math class converts an angle measured in degrees to an approximately equivalent angle measured in radian.

Syntax:

public static double toRadians (double angdeg)

Parameters

The parameter ‘angdeg’ represents an angle measured in degrees.

Return Value:

The toRadians() method returns the an inexact angdeg measurement in radians.

Example 1:

public class JavaMathToRadiansExample1 {
    public static void main(String[] args) {
        double a=67;
        //converts a degree angle to an approximately equivalent angle measured in radian
        System.out.println("Degree Angle "+ a+" converted in radian = "+Math.toRadians(a));
    }
}

Output:

Degree Angle 67.0 converted in radian = 1.1693705988362009

Example 2:

public class JavaMathToRadiansExample2 {
    public static void main(String[] args) {
        double a=Double.MIN_VALUE;
        //converts a degree angle to an approximately equivalent angle measured in radian
        System.out.println("Degree Angle "+ a+" converted in radian = "+Math.toRadians(a));
    }
}

Output:

Degree Angle 4.9E-324 converted in radian = 0.0

Example 3:

public class JavaMathToRadiansExample3 {
    public static void main(String[] args) {
        double a=-0d;
        //converts a degree angle to an approximately equivalent angle measured in radian
        System.out.println("Degree Angle "+ a+" converted in radian = "+Math.toRadians(a));
    }
}

Output:

Degree Angle -0.0 converted in radian = -0.0

Example 4:

public class JavaMathToRadiansExample4 {
    public static void main(String[] args) {
        double a=Double.NaN;
        //returns NaN, if the argument passed is NaN
        System.out.println("Degree Angle "+ a+" converted in radian = "+Math.toRadians(a));
    }
}

Output:

Degree Angle NaN converted in radian = NaN

Example 5:

public class JavaMathToRadiansExample5 {
    public static void main(String[] args) {
        double a=Double.NEGATIVE_INFINITY;
        //returns negative -infinity, if the argument passed is negative infinity
        System.out.println("Degree Angle "+ a+" converted in radian = "+Math.toRadians(a));
    }
}

Output:

Degree Angle -Infinity converted in radian = -Infinity
