Java.math.BigInteger.pow() Method
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
