某個 BigInteger 值除以另一個值，並且傳回結果。

public:
 static System::Numerics::BigInteger Divide(System::Numerics::BigInteger dividend, System::Numerics::BigInteger divisor);
public static System.Numerics.BigInteger Divide (System.Numerics.BigInteger dividend, System.Numerics.BigInteger divisor);
static member Divide : System.Numerics.BigInteger * System.Numerics.BigInteger -> System.Numerics.BigInteger
Public Shared Function Divide (dividend As BigInteger, divisor As BigInteger) As BigInteger

參數

dividend
BigInteger

做為被除數的值。

divisor
BigInteger

做為除數的值。

傳回

BigInteger

相除的商數。

例外狀況

DivideByZeroException

divisor 是 0 (零)。

範例

下列範例會建立 值的陣列 BigInteger 。 然後它會使用每個元素做為使用 Divide 方法的除法運算中的商數、除法運算子 (/) 和 DivRem 方法。

using System;
using System.Numerics;

   public static void Main()
   {
      BigInteger divisor = BigInteger.Pow(Int64.MaxValue, 2);

                                 divisor + BigInteger.One };

      // Divide each dividend by divisor in three different ways.
      foreach (BigInteger dividend in dividends)
      {

備註

方法 Divide 會執行整數除法;捨棄除法所產生的任何餘數。 若要在保留餘數的同時執行整數除法，請呼叫 DivRem 方法。 若要只擷取其餘部分，請呼叫 Remainder 方法。

方法 Divide 可由不支援運算子多載的語言使用。 其行為與使用除法運算子的除法相同。
