java.math.BigInteger.modPow(BigInteger exponent, BigInteger m)

Description Of BigInteger: modPow(BigInteger exponent, BigInteger m)

The java.math.BigInteger.modPow(BigInteger exponent, BigInteger m) returns a BigInteger whose value is (this^exponent mod m) . (Unlike pow , this method permits negative exponents.)

BigInteger.modPow(BigInteger exponent, BigInteger m) method returns this^exponent mod m

Code Example Java BigInteger

import java.math.BigInteger;

public class BigIntegerExam {
 public static void main(String[] args) {
  BigInteger exponent = new BigInteger("3");

  BigInteger bi1 = new BigInteger("2");
  BigInteger bi2 = new BigInteger("5");

  // perform modPow operation on bi1 using bi2 and exp
  BigInteger bi3 = bi1.modPow(exponent, bi2); // 2^3 % 5

  System.out.println(bi3); // output 3
 }
}
