回傳一個值，表示某指定 Decimal 是否小於另一指定 Decimal。

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

參數

d1
Decimal

第一個要比較的值。

d2
Decimal

要比較的第二個值。

傳回

Boolean

true若d1小於d2;否則，。 false

實作

LessThan(TSelf, TOther)

備註

此 LessThan 方法定義了小於運算子對 Decimal 值的運算。 它啟用了以下程式碼：

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

open System

let number1 = 16354.0699m
let number2 = 16354.0695m
printfn $"{number1} < {number2}: {number1 < number2}"

let rounded1 = Decimal.Round(number1, 2)
let rounded2 = Decimal.Round(number2, 2)
printfn $"{rounded1} < {rounded2}: {rounded1 < rounded2}"

// 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

不支援自訂運算子的語言則可直接呼叫該 Compare 方法。 他們也可能直接呼叫該 LessThan 方法，如下範例所示。

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

此運算子的等價方法為 Decimal.Compare(Decimal, Decimal)
