Advertisements


Description

The java.math.BigInteger.pow(int exponent) returns a BigInteger whose value is (thisexponent). The exponent is an integer rather than a BigInteger.

Declaration

Following is the declaration for java.math.BigInteger.pow() method

public BigInteger pow(int exponent)

Parameters

  • exponent - exponent to which this BigInteger is to be raised

Return Value

This method returns a BigInteger object whose value is thisexponent.

Exception

  • ArithmeticException - exponent is negative. This would cause the operation to yield a non-integer value.

Example

The following example shows the usage of math.BigInteger.pow() method

package com.tutorialspoint;

import java.math.*;

public class BigIntegerDemo {

public static void main(String[] args) {

	// create 2 BigInteger objects
	BigInteger bi1, bi2;

	// create and assign value to exponent
	int exponent = 2;

	// assign value to bi1
	bi1 = new BigInteger("6");

	// perform pow operation on bi1 using exponent
	bi2 = bi1.pow(exponent);

	String str = "Result is " + bi1 + "^" +exponent+ " = " +bi2;

	// print bi2 value
	System.out.println( str );
   }
}

Let us compile and run the above program, this will produce the following result:

Result is 6^2 = 36
