Führt die Ganzzahldivision von zwei BigInteger-Werten aus und gibt den Rest zurück.

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

Parameter

dividend: BigInteger

Der zu dividierende Wert.

divisor: BigInteger

Der Wert, durch den dividiert werden soll.

Gibt zurück

BigInteger

Der Rest aus der Division von dividend durch divisor.

Ausnahmen

DivideByZeroException

divisor ist 0 (null).

Beispiele

Im folgenden Beispiel wird der Rest der Methode mit dem DivRem Rest verglichen, der von der Remainder -Methode zurückgegeben wird, um festzustellen, dass die beiden Methoden identische Reste berechnen.

Hinweise

Das Vorzeichen des restlichen Werts ist das Zeichen des dividend Parameters.

Die Remainder -Methode wird für Sprachen implementiert, die keine benutzerdefinierten Operatoren unterstützen. Sein Verhalten ist identisch mit der Division mit dem Modulus-Operator.

Bei Bedarf führt die Methode automatisch eine implizite Konvertierung anderer integraler Typen in Objekte durch BigInteger , bevor sie den Modulusvorgang ausführt.
