Source:: BigInteger.cs

Source:: BigInteger.cs

Computes the quotient and remainder of two values.

public:
 static ValueTuple<System::Numerics::BigInteger, System::Numerics::BigInteger> DivRem(System::Numerics::BigInteger left, System::Numerics::BigInteger right) = System::Numerics::IBinaryInteger<System::Numerics::BigInteger>::DivRem;

public static (System.Numerics.BigInteger Quotient, System.Numerics.BigInteger Remainder) DivRem (System.Numerics.BigInteger left, System.Numerics.BigInteger right);

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)

Parameters

left: BigInteger

The value that right divides.

right: BigInteger

The value that divides left.

Returns

ValueTuple<BigInteger,BigInteger>

The quotient and remainder of left divided-by right.

Implements

DivRem(TSelf, TSelf)

Applies to

DivRem(BigInteger, BigInteger, BigInteger)

Source:: BigInteger.cs

Source:: BigInteger.cs

Source:: BigInteger.cs

Divides one BigInteger value by another, returns the result, and returns the remainder in an output parameter.

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

Parameters

dividend: BigInteger

The value to be divided.

divisor: BigInteger

The value to divide by.

remainder: BigInteger

When this method returns, contains a BigInteger value that represents the remainder from the division. This parameter is passed uninitialized.

Returns

BigInteger

The quotient of the division.

Exceptions

DivideByZeroException

divisor is 0 (zero).

Examples

The following example creates an array of BigInteger values. It then uses each element as the quotient in a division operation that uses the Divide method, the division operator (/), and the DivRem method.

using System.Numerics;

Remarks

This method preserves both the quotient and the remainder that results from integer division. If you are not interested in the remainder, use the Divide method or the division operator; if you are only interested in the remainder, use the Remainder method.

The sign of the returned remainder value is the same as the sign of the dividend parameter.

The behavior of the DivRem method is identical to that of the Math.DivRem method.
