Java Math Function Example

Hello Friends,

Hope you will like this article.

In this article we will be familiar with maths functions of java. Here example is given and by running this example code to your pc, you will easily get and be familiar with all these functions.

package mathsfunctions;

public class MathsFunctions {

    public static void main(String args[]){

    int i = 2;

    int j = -4;

    double x = 19.8;

    double y = 0.38;

    System.out.println("i is " + i);

    System.out.println("j is " + j);

    System.out.println("x is " + x);

    System.out.println("y is " + y);
