Decimal.Compare メソッド
指定した 2 つの Decimal 値を比較します。
Public Shared Function Compare( _
ByVal d1 As Decimal, _ ByVal d2 As Decimal _) As Integer
[C#]
public static int Compare(decimald1,decimald2);
[C++]
public: static int Compare(Decimald1,Decimald2);
[JScript]
public static function Compare(
d1 : Decimal,d2 : Decimal) : int;
パラメータ
戻り値
d1 と d2 の相対値を示す符号付き数値。
| 戻り値 | 意味 |
|---|---|
| 0 より小さい値 | d1 は d2 より小さい値です。 |
| 0 | d1 と d2 は等値です。 |
| 0 より大きい値 | d1 が d2 より大きい値です。 |
