Decimal.LessThan(Decimal, Decimal) 演算子

定義

指定した Decimal が、指定した別の Decimal より小さいかどうかを示す値を返します。Returns a value indicating whether a specified Decimal is less than another specified Decimal.

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

比較する最初の値です。The first value to compare.

d2
Decimal

比較する 2 番目の値です。The second value to compare.

戻り値

d1d2 より小さい場合は true。それ以外の場合は falsetrue 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)
