Decimal.op_Modulus メソッド

指定した 2 つの Decimal 値を除算した結果の剰余を返します。

名前空間: System
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Public Shared Operator Mod
 ( _
    d1 As Decimal, _
    d2 As Decimal _
) As Decimal

Visual Basic (使用法)

Dim d1 As Decimal
Dim d2 As Decimal
Dim returnValue As Decimal

returnValue = (d1 Mod d2)

public static decimal operator % (
    decimal d1,
    decimal d2
)

C++

public:
static Decimal operator % (
    Decimal d1, 
    Decimal d2
)

J# では、オーバーロードされた演算子は使用できません。

JScript

JScriptでは、 オーバーロードされた演算子は使用できますが、新規に宣言することはできません。

パラメータ

d1: Decimal (被除数)。

d2: Decimal (除数)。

戻り値
d1 を d2 で除算した結果の Decimal 剰余。

例外

例外の種類	条件
DivideByZeroException	d2 が zero です。
OverflowException	戻り値が MinValue より小さい値か、MaxValue より大きい値です。

使用例

Decimal 値の複数のペアを作成し、各ペアの剰余を Modulus 演算子で計算するコード例を次に示します。
