static member DivRem : System.Numerics.BigInteger * System.Numerics.BigInteger -> ValueTuple<System.Numerics.BigInteger, System.Numerics.BigInteger>

Public Shared Function DivRem (left As BigInteger, right As BigInteger) As ValueTuple(Of BigInteger, BigInteger)

Parâmetros

left: BigInteger

O valor que right se divide.

right: BigInteger

O valor que divide left.

Retornos

ValueTuple<BigInteger,BigInteger>

O quociente e o restante de left dividido por right.

Implementações

Aplica-se a

DivRem(BigInteger, BigInteger, BigInteger)

Origem:: BigInteger.cs

Origem:: BigInteger.cs

Origem:: BigInteger.cs

Divide um valor BigInteger por outro, retorna o resultado e retorna o restante em um parâmetro de saída.

public:
 static System::Numerics::BigInteger DivRem(System::Numerics::BigInteger dividend, System::Numerics::BigInteger divisor, [Runtime::InteropServices::Out] System::Numerics::BigInteger % remainder);

public static System.Numerics.BigInteger DivRem (System.Numerics.BigInteger dividend, System.Numerics.BigInteger divisor, out System.Numerics.BigInteger remainder);

static member DivRem : System.Numerics.BigInteger * System.Numerics.BigInteger * BigInteger -> System.Numerics.BigInteger

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

Parâmetros

dividend: BigInteger

O valor a ser dividido.

divisor: BigInteger

O valor pelo qual dividir.

remainder: BigInteger

Quando este método retorna, contém um valor BigInteger que representa o restante da divisão. Este parâmetro é passado não inicializado.

Retornos

BigInteger

O quociente da divisão.

Exceções

DivideByZeroException

divisor é 0 (zero).

Exemplos

O exemplo a seguir cria uma matriz de BigInteger valores. Em seguida, ele usa cada elemento como o quociente em uma operação de divisão que usa o Divide método , o operador de divisão (/) e o DivRem método .

Comentários

Esse método preserva o quociente e o restante resultante da divisão de inteiros. Se você não estiver interessado no restante, use o Divide método ou o operador de divisão; se você estiver interessado apenas no restante, use o Remainder método .

O sinal do valor retornado remainder é o mesmo que o sinal do dividend parâmetro .

O comportamento do DivRem método é idêntico ao do Math.DivRem método .
