C# BigInteger ModPow

Description

BigInteger ModPow Performs modulus division on a number raised to the power of another number.

Syntax

BigInteger.ModPow has the following syntax.

public static BigInteger ModPow(
  BigInteger value,//  ww w  .  j av  a 2 s .c om
  BigInteger exponent,
  BigInteger modulus
)

Parameters

BigInteger.ModPow has the following parameters.

• value - The number to raise to the exponent power.
• exponent - The exponent to raise value by.
• modulus - The number by which to divide value raised to the exponent power.

Returns

BigInteger.ModPow method returns The remainder after dividing valueexponent by modulus.

Example

using System;/*  w w w .java2  s  .  c  o  m*/
using System.Numerics;

public class Class1
{
   public static void Main()
   {
      BigInteger number = 10;
      int exponent = 3;
      BigInteger modulus = 30;
      Console.WriteLine("({0}^{1}) Mod {2} = {3}", 
                        number, exponent, modulus, 
                        BigInteger.ModPow(number, exponent, modulus));    
   }
}

The code above generates the following result.
