BigInteger.ModPow(BigInteger, BigInteger, BigInteger) 方法

public:
 static System::Numerics::BigInteger ModPow(System::Numerics::BigInteger value, System::Numerics::BigInteger exponent, System::Numerics::BigInteger modulus);

public static System.Numerics.BigInteger ModPow(System.Numerics.BigInteger value, System.Numerics.BigInteger exponent, System.Numerics.BigInteger modulus);

static member ModPow : System.Numerics.BigInteger * System.Numerics.BigInteger * System.Numerics.BigInteger -> System.Numerics.BigInteger

Public Shared Function ModPow (value As BigInteger, exponent As BigInteger, modulus As BigInteger) As BigInteger

参数

返回

除valuemodulus以指数后的余数。

例外

示例

以下示例提供了调用 ModPow 该方法的简单插图。

using System;
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 example displays the following output:
//      (10^3) Mod 30 = 10

open System.Numerics;

let number = 10I;
let exponent = 3;
let modulus = 30I;
printfn $"({number}^{exponent}) Mod {modulus} = {BigInteger.ModPow(number, exponent, modulus)}"
// The example displays the following output:
//      (10^3) Mod 30 = 10

Imports System.Numerics

Module Example
   Public Sub Main()
      Dim number As BigInteger = 10
      Dim exponent As Integer = 3
      Dim modulus As BigInteger = 30
      Console.WriteLine("({0}^{1}) Mod {2} = {3}", _
                        number, exponent, modulus, _
                        BigInteger.ModPow(number, exponent, modulus))
   End Sub   
End Module
' The example displays the following output:
'       (10^3) Mod 30 = 10

注解

该方法 ModPow 计算以下表达式：

（baseValue ^ 指数）Mod modulus

若要对 BigInteger 不带模数除法的值执行指数化，请使用 Pow 该方法。
