Explanation:

•The java.lang.Math.pow() is used to calculate a number raise to the power of some other number. This function accepts two parameters and returns the value of first parameter raised to the second parameter. There are some special cases as listed below:

If the second parameter is positive or negative zero then the result will be 1.0.

If the second parameter is 1.0 then the result will be same as that of the first parameter.

If the second parameter is NaN then the result will also be NaN.

Syntax:

public static double pow(double a, double b)

Parameter:

a : this parameter is the base

b : this parameter is the exponent.

Return :

This method returns ab.

Example 1: To show working of java.lang.Math.pow() method.

// Java program to demonstrate working

// of java.lang.Math.pow() method

import java.lang.Math;

class Gfg {

// driver code

public static void main(String args[])

{

double a = 30;

double b = 2;

System.out.println(Math.pow(a, b));

a = 3;

b = 4;

System.out.println(Math.pow(a, b));

a = 2;

b = 6;

System.out.println(Math.pow(a, b));

}

}

Output:

900.0

81.0

64.0

Example 2: To show working of java.lang.Math.pow() method when argument is NaN.

// Java program to demonstrate working

// of java.lang.Math.pow() method

import java.lang.Math; // importing java.lang package

public class GFG {

public static void main(String[] args)

{

double nan = Double.NaN;

double result;

// Here second argument is NaN,

// output will be NaN

result = Math.pow(2, nan);

System.out.println(result);

// Here second argument is zero

result = Math.pow(1254, 0);

System.out.println(result);

// Here second argument is one

result = Math.pow(5, 1
