Byte から Decimal への変換
8 ビット符号なし整数を Decimal に変換します。
returnValue = Decimal.op_Implicit(value)
[C#]
public static implicit operator decimal(bytevalue);
[C++]
public: static Decimal op_Implicit(unsigned charvalue);
[JScript]
returnValue = value;
[Visual Basic] Visual Basic では、この型で定義されている型変換を使用することができます。ただし、独自に定義することはできません。
[JScript] JScript では、この型で定義されている型変換を使用することができます。ただし、独自に定義することはできません。
引数 [Visual Basic, JScript]
- value
8 ビット符号なし整数。
パラメータ [C#, C++]
- value
8 ビット符号なし整数。
戻り値
変換された 8 ビット符号なし整数を表す Decimal 。
使用例
[Visual Basic, C#, C++] Byte to Decimal 変換を使用して Byte の値を Decimal の数値に変換するコード例を次に示します。この変換は C# では暗黙で行われますが、Visual Basic および C++ では op_Implicit 演算子が必要です。これらの言語では、 Decimal への暗黙の変換には、他のメソッドが使用されます。
