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:
double java.lang.Math.pow(double a, double b)
Math pow() method in Java with example...!!! Share on X
Examples
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:
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.
