It’s very basic in Arithmetic to do the ‘power of a number’. What this means is that a number will be multiplied as many times as what the power is. In this post, we will learn how to power a number in Java using Math.pow()
Signature:
1 | double java.lang.Math.pow(double a, double b) |

Examples
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | import java.lang.Math; public class Math_pow_example { public static void main(String args[]) { int intResult; double doubleResult; double nan = Double.NaN; //power argument is 4 on a integer //pow() by definition requires double as arguments. if you use integer, then you need to cast it like below. intResult = (int) Math.pow(5, 4); System.out.println(intResult); //power argument is 8.2 on a double doubleResult = Math.pow(7.6, 8.2); System.out.println(doubleResult); //power argument is one doubleResult = Math.pow(7, 1); System.out.println(doubleResult); //power argument is Nan doubleResult = Math.pow(10, nan); System.out.println(doubleResult); //power argument is zero doubleResult = Math.pow(55, 0); System.out.println(doubleResult); } } |
Output:
1 2 3 4 5 | 625 1.6698269141545841E7 7.0 NaN 1.0 |
I hope this article will help you in understanding how to get the power of a number in Java.
