BigInteger.Division(BigInteger, BigInteger) Operator

Definicja

Dzieli określoną BigInteger wartość przez inną określoną BigInteger wartość przy użyciu dzielenia całkowitego.

public:
 static System::Numerics::BigInteger operator /(System::Numerics::BigInteger dividend, System::Numerics::BigInteger divisor);
public:
 static System::Numerics::BigInteger operator /(System::Numerics::BigInteger dividend, System::Numerics::BigInteger divisor) = System::Numerics::IDivisionOperators<System::Numerics::BigInteger, System::Numerics::BigInteger, System::Numerics::BigInteger>::op_Division;
public static System.Numerics.BigInteger operator / (System.Numerics.BigInteger dividend, System.Numerics.BigInteger divisor);
static member ( / ) : System.Numerics.BigInteger * System.Numerics.BigInteger -> System.Numerics.BigInteger
Public Shared Operator / (dividend As BigInteger, divisor As BigInteger) As BigInteger

Parametry

dividend
BigInteger

Wartość, która ma zostać podzielona.

divisor
BigInteger

Wartość do dzielenia według.

Zwraca

Całkowity wynik podziału.

Implementuje

Wyjątki

divisor ma wartość 0 (zero).

Przykłady

Poniższy przykład tworzy tablicę BigInteger wartości. Następnie używa każdego elementu jako ilorazu w operacji dzielenia, która używa Divide metody, operatora dzielenia (/) i DivRem metody.

using System;
using System.Numerics;

                                 divisor + BigInteger.One };

      // Divide each dividend by divisor in three different ways.
      foreach (BigInteger dividend in dividends)
      {
         BigInteger quotient;
         BigInteger remainder = 0;

Uwagi

Metoda Division definiuje operację dzielenia dla BigInteger wartości. Umożliwia stosowanie kodu takiego jak następujący:

BigInteger num1 = 100045632194;
BigInteger num2 = 90329434;
BigInteger quotient = num1 / num2;
let num1 = 100045632194I
let num2 = 90329434I
let quotient = num1 / num2
Dim num1 As BigInteger = 100045632194
Dim num2 As BigInteger = 90329434
Dim quotient As BigInteger = num1 / num2

Języki, które nie obsługują operatorów niestandardowych i przeciążenia operatorów, mogą zamiast tego wywoływać metodę Divide .

Równoważna metoda dla tego operatora to BigInteger.Divide(BigInteger, BigInteger)
