BigInteger.Remainder(BigInteger, BigInteger) 方法

定義

對兩個 BigInteger 值執行整數除法運算,並傳回餘數。

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

參數

dividend
BigInteger

做為被除數的值。

divisor
BigInteger

做為除數的值。

傳回

dividend 除以 divisor 後的餘數。

例外狀況

divisor 是 0 (零)。

範例

下列範例會比較 方法的 DivRem 餘數與 方法傳 Remainder 回的餘數,以建立兩個方法計算相同的餘數。

using System.Numerics;

備註

餘數的正負號是 參數的 dividend 正負號。

針對不支援自定義運算符的語言,會 Remainder 實作 方法。 其行為與使用模數運算符的除法相同。

如有必要,方法會在執行模數運算之前,自動對物件執行其他整數類型的 BigInteger 隱含轉換。
