In this post, we will learn how to perform mathematical operations on numbers – power, squre root, floor, ceil, rounding numbers Here is the program that illustrates various mathematical operations in Java.
 
package numbers;

/**

public class Maths {

    public static void main(String [] args) throws Exception {

        //Get absolute value
        System.out.println("Absolute value of -2929.2 -> " + Math.abs(-2929.2));

        //Rounding to 0 decimals
        System.out.println("Round of the number -234.221 is ->" +
                " " + Math.round(-234.221));

        //Power method
        System.out.println("2^3 is -> " +  Math.pow(2, 3));

        //Finding square root
        System.out.println("Square root of 525 -> " + Math.sqrt(525));

        //Get random value
        System.out.println("Random number -> " + String.valueOf(Math.random()));

    }

}
Here is the output of above example.

Absolute value of -2929.2 -> 2929.2
Round of the number -234.221 is -> -234
2^3 is -> 8.0
Square root of 525 -> 22.9128784747792
Random number -> 0.6005728946831648
