Calculate power with Math pow

In this example we shall show you how to calculate the power of a number using the pow(double a, double b)  API method of Math Class. The class Math contains methods for performing basic numeric operations such as the elementary exponential, logarithm, square root, and trigonometric functions. To calculate the power of a number one should perform the following steps:

  • Call the pow(double a, double b) method. The method takes two double parameters. The first argument is the number that will be raised and the second one is the power. So, double a is raised to the power of b,

as described in the code snippet below.  

package com.javacodegeeks.snippets.core;

public class CalculatePowerWithMathPow {
	public static void main(String[] args) {
		// raises 3 to 2 which equals with 9
		// raises -2 to 2 which equals with 4
		// raises 2.5 to 3 which equals with 6.25




This was an example of how to calculate the power of a number using the pow(double a, double b) API method of Math Class in Java.
