2 つの BigInteger 値に対する整数除算を実行し、その剰余を返します。

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

パラメーター

dividend
BigInteger

被除数。

divisor
BigInteger

除数。

戻り値

BigInteger

dividend を divisor で除算した結果生じた剰余。

例外

DivideByZeroException

divisor が 0 (ゼロ) です。

例

次の例では、 メソッドの DivRem 剰余を メソッドから Remainder 返される剰余と比較して、2 つのメソッドが同じ剰余を計算することを確認します。

using System.Numerics;

注釈

剰余の符号は、 パラメーターの dividend 符号です。

メソッドは Remainder 、カスタム演算子をサポートしていない言語に対して実装されます。 その動作は、剰余演算子を使用した除算と同じです。

必要に応じて、メソッドは他の整数型からオブジェクトへの暗黙的な変換を自動的に BigInteger 実行してから、剰余演算を実行します。
