对两个 BigInteger 值执行整除并返回余数。

public:
 static System::Numerics::BigInteger Remainder(System::Numerics::BigInteger dividend, System::Numerics::BigInteger divisor);

public static System.Numerics.BigInteger Remainder (System.Numerics.BigInteger dividend, System.Numerics.BigInteger divisor);

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

Public Shared Function Remainder (dividend As BigInteger, divisor As BigInteger) As BigInteger

参数

dividend: BigInteger

要作为被除数的值。

divisor: BigInteger

要作为除数的值。

BigInteger

将 dividend 除以 divisor 后的余数。

例外

DivideByZeroException

divisor 是 0（零）。

示例

以下示例将方法中的余数 DivRem 与方法返回 Remainder 的余数进行比较，以确定这两种方法计算相同的余数。

using System;
using System.Numerics;

   public static void Main()
   {
      BigInteger dividend1 = BigInteger.Pow(Int64.MaxValue, 3);

      BigInteger divisor2 = divisor1 * BigInteger.MinusOne;
      BigInteger remainder1, remainder2;
      BigInteger divRem1 = BigInteger.Zero;
      BigInteger divRem2 = BigInteger.Zero;

      remainder1 = BigInteger.Remainder(dividend1, divisor1);
      remainder2 = BigInteger.Remainder(dividend2, divisor1);

      BigInteger.DivRem(dividend1, divisor1, out divRem1);
      Console.WriteLine("BigInteger.Remainder({0}, {1}) = {2}",
                        dividend1, divisor1, remainder1);
      Console.WriteLine("BigInteger.DivRem({0}, {1}) = {2}",
                        dividend1, divisor1, divRem1);
      if (remainder1.Equals(divRem1))
         Console.WriteLine("The remainders are equal.\n");

      BigInteger.DivRem(dividend2, divisor2, out divRem2);
      Console.WriteLine("BigInteger.Remainder({0}, {1}) = {2}",
                        dividend2, divisor2, remainder2);

注解

余数的符号是参数的 dividend 符号。

方法 Remainder 针对不支持自定义运算符的语言实现。其行为与使用模数运算符的除法相同。

如有必要，方法在执行模量运算之前，会自动将其他整型类型隐 BigInteger 式转换为对象。
