BigInteger.Remainder(BigInteger, BigInteger) Metodo

Definizione

Esegue una divisione intera su due valori BigInteger e restituisce il resto.

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

Parametri

dividend
BigInteger

Valore da dividere.

divisor
BigInteger

Valore per cui dividere.

Restituisce

Resto risultante dalla divisione di dividend per divisor.

Eccezioni

divisor è 0 (zero).

Esempio

Nell'esempio seguente viene confrontato il resto del DivRem metodo con il resto restituito dal Remainder metodo per stabilire che i due metodi calcolano resto identici.

Commenti

Il segno del resto è il segno del dividend parametro .

Il Remainder metodo viene implementato per le lingue che non supportano operatori personalizzati. Il comportamento è identico alla divisione usando l'operatore modulo.

Se necessario, il metodo esegue automaticamente la conversione implicita di altri tipi integrali in BigInteger oggetti prima di eseguire l'operazione modulo.
