Public Shared Function DivRem (dividend As BigInteger, divisor As BigInteger, ByRef remainder As BigInteger) As BigInteger

Parameter

dividend
BigInteger

Der zu dividierende Wert.

divisor
BigInteger

Der Wert, durch den dividiert werden soll.

remainder

Die Rückgabe dieser Methode enthält einen BigInteger-Wert, der den Rest der Division darstellt. Dieser Parameter wird nicht initialisiert übergeben.

Gibt zurück

Der Quotient der Division.

Ausnahmen

divisor ist 0 (null).

Beispiele

Im folgenden Beispiel wird ein Array von BigInteger Werten erstellt. Anschließend wird jedes Element als Quotient in einem Divisionsvorgang verwendet, der die Divide -Methode, den Divisionoperator (/) und die DivRem -Methode verwendet.

Hinweise

Diese Methode behält sowohl den Quotienten als auch den Rest bei, der sich aus der Ganzzahlteilung ergibt. Wenn Sie sich nicht für den Rest interessieren, verwenden Sie die Divide Methode oder den Divisionoperator. Wenn Sie nur an dem rest interessiert sind, verwenden Sie die Remainder -Methode.

Das Vorzeichen des zurückgegebenen remainder Werts ist mit dem Zeichen des dividend Parameters identisch.

Das Verhalten der DivRem -Methode ist identisch mit dem der Math.DivRem -Methode.
