.pow()

The Math.pow() method returns a double value of the first argument raised to the power of the second argument.

Math.pow(base, exponent)

The base and exponent arguments are both double values.

It’s important to note that edge cases with special arguments such as 0.0, infinity， or NaN will produce special results as shown in the example below.

The following example uses Math.pow() to return 3.0 raised to the power of 2.0:

public class Main {
  public static void main(String[] args) {

    double base = 3.0;
    double exponent = 2.0;

    System.out.println(Math.pow(base, exponent));

    System.out.println(Math.pow(base, 0.0));

    System.out.println(Math.pow(0.0, exponent));

    double notANumber = Double.NaN;
    double negInfinity = Double.NEGATIVE_INFINITY;

    System.out.println(Math.pow(notANumber, exponent));

    System.out.println(Math.pow(0.0, negInfinity));
  }
}

This will produce the following output:

9.0
1.0
0.0
NaN
Infinity
