# Decimal.LessThan(Decimal, Decimal)Decimal.LessThan(Decimal, Decimal)Decimal.LessThan(Decimal, Decimal)Decimal.LessThan(Decimal, Decimal) Operator

## 定義

``````public:
static bool operator <(System::Decimal d1, System::Decimal d2);``````
``public static bool operator < (decimal d1, decimal d2);``
``static member ( < ) : decimal * decimal -> bool``
``Public Shared Operator < (d1 As Decimal, d2 As Decimal) As Boolean``

#### パラメーター

d1
Decimal Decimal Decimal Decimal

d2
Decimal Decimal Decimal Decimal

#### 戻り値

`d1``d2` より小さい場合は `true`。それ以外の場合は `false``true` if `d1` is less than `d2`; otherwise, `false`.

## 注釈

メソッドLessThanは、値のDecimal小なり演算子の演算を定義します。The LessThan method defines the operation of the less than operator for Decimal values. 次のようなコードが有効になります。It enables code such as the following:

``````using System;

public class Example
{
public static void Main()
{
Decimal number1 = 16354.0699m;
Decimal number2 = 16354.0695m;
Console.WriteLine("{0} < {1}: {2}", number1,
number2, number1 < number2);

number1 = Decimal.Round(number1, 2);
number2 = Decimal.Round(number2, 2);
Console.WriteLine("{0} < {1}: {2}", number1,
number2, number1 < number2);
}
}
// The example displays the following output:
//       16354.0699 < 16354.0695: False
//       16354.07 < 16354.07: False
``````
``````Module Example
Public Sub Main()
Dim number1 As Decimal = 16354.0699d
Dim number2 As Decimal = 16354.0695d
Console.WriteLine("{0} < {1}: {2}", number1,
number2, number1 < number2)

number1 = Decimal.Round(number1, 2)
number2 = Decimal.Round(number2, 2)
Console.WriteLine("{0} < {1}: {2}", number1,
number2, number1 < number2)
End Sub
End Module
' The example displays the following output:
'       16354.0699 < 16354.0695: False
'       16354.07 < 16354.07: False
``````

カスタム演算子をサポートしない言語では、 Compare代わりにメソッドを呼び出すことができます。Languages that do not support custom operators can call the Compare method instead. また、次の例に示すようLessThanに、メソッドを直接呼び出すこともできます。They may also be able to call the LessThan method directly, as the following example shows.

``````Module Example
Public Sub Main()
Dim number1 As Decimal = 16354.0699d
Dim number2 As Decimal = 16354.0695d
Console.WriteLine("{0} < {1}: {2}", number1, number2,
Decimal.op_LessThan(number1, number2))

number1 = Decimal.Round(number1, 2)
number2 = Decimal.Round(number2, 2)
Console.WriteLine("{0} < {1}: {2}", number1, number2,
Decimal.op_LessThan(number1, number2))
End Sub
End Module
' The example displays the following output:
'       16354.0699 < 16354.0695: False
'       16354.07 < 16354.07: False
``````

この演算子の同等の方法は次のようになります。Decimal.Compare(Decimal, Decimal)The equivalent method for this operator is Decimal.Compare(Decimal, Decimal)
