BigInteger.Remainder(BigInteger, BigInteger) Método

Definição

Namespace:

System.Numerics

Assembly:

System.Runtime.Numerics.dll

Origem:

BigInteger.cs

Executa a divisão do inteiro em dois valores BigInteger e retorna o restante.

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

Parâmetros

dividend

BigInteger

O valor a ser dividido.

divisor

BigInteger

O valor pelo qual dividir.

Retornos

BigInteger

O resto após dividir dividend por divisor.

Exceções

DivideByZeroException

divisor é 0 (zero).

Exemplos

O exemplo a seguir compara o restante do DivRem método com o restante retornado pelo Remainder método para estabelecer que os dois métodos calculam restos idênticos.

Comentários

O sinal do restante é o sinal do dividend parâmetro .

O Remainder método é implementado para idiomas que não dão suporte a operadores personalizados. Seu comportamento é idêntico à divisão usando o operador modulus.

Se necessário, o método executa automaticamente a conversão implícita de outros tipos integrais em BigInteger objetos antes de executar a operação de módulo.
