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_LessThanOrEqual;
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
要比較的第一個值。
- d2
- Decimal
要比較的第二個值。
傳回
如果 d1
小於或等於 d2
,則為 true
;否則為 false
。
實作
備註
方法 LessThanOrEqual 會針對值定義小於或等於運算子 Decimal 的作業。 它會啟用下列程式碼:
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: True
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: True
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: True
不支援自訂運算子的語言可以改為呼叫 Compare 方法。 它們也可以直接呼叫 LessThanOrEqual 方法,如下列範例所示。
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_LessThanOrEqual(number1, number2))
number1 = Decimal.Round(number1, 2)
number2 = Decimal.Round(number2, 2)
Console.WriteLine("{0} <= {1}: {2}", number1, number2,
Decimal.op_LessThanOrEqual(number1, number2))
End Sub
End Module
' The example displays the following output:
' 16354.0699 >= 16354.0695: False
' 16354.07 >= 16354.07: True
這個運算子的對等方法為 Decimal.Compare(Decimal, Decimal)
