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

Visual Basic (宣言)

Public Shared Function Compare
 ( _
    d1 As Decimal, _
    d2 As Decimal _
) As Integer

Visual Basic (使用法)

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

returnValue = Decimal.Compare(d1, d2)

C#

public static int Compare
 (
    decimal d1,
    decimal d2
)

C++

public:
static int Compare (
    Decimal d1, 
    Decimal d2
)

J#

public static int Compare
 (
    Decimal d1, 
    Decimal d2
)

JScript

public static function Compare
 (
    d1 : decimal, 
    d2 : decimal
) : int

パラメータ

d1

Decimal。

d2

Decimal。

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 が d2 より小さい。
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。
