# BigInteger.DivRem(BigInteger, BigInteger, BigInteger) メソッド

## 定義

ある BigInteger 値を別の値で除算し、その結果を返します。剰余は出力パラメーターとして返されます。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``

#### パラメーター

dividend
BigInteger

divisor
BigInteger

remainder
BigInteger

このメソッドから制御が戻るときに、除算の剰余を表す　BigInteger 値が格納されます。When this method returns, contains a BigInteger value that represents the remainder from the division. このパラメーターは初期化せずに渡されます。This parameter is passed uninitialized.

#### 例外

`divisor` が 0 (ゼロ) です。`divisor` is 0 (zero).

## 注釈

このメソッドは、整数除算によって得られる商と剰余の両方を保持します。This method preserves both the quotient and the remainder that results from integer division. 残りの部分に関心がない場合は、Divide メソッドまたは除算演算子を使用します。残りの部分のみに関心がある場合は、Remainder メソッドを使用します。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.

DivRem メソッドの動作は、Math.DivRem メソッドの動作と同じです。The behavior of the DivRem method is identical to that of the Math.DivRem method.
