Decimal.LessThanOrEqual(Decimal, Decimal) 操作员

定义

命名空间:

System

程序集:

System.Runtime.dll

Source:

Decimal.cs

返回一个值，该值指示指定的 Decimal 是小于还是等于另一个指定的 Decimal。

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

参数

d1

Decimal

要比较的第一个值。

d2

Decimal

要比较的第二个值。

返回

Boolean

如果 d1 小于等于 d2，则为 true；否则为 false。

实现

LessThanOrEqual(TSelf, TOther)

注解

方法 LessThanOrEqual 定义值的小于或等于运算符的 Decimal 运算。 它启用如下代码：

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

不支持自定义运算符的语言可以改为调用 Compare 方法。 他们还可以直接调用 LessThanOrEqual 方法，如以下示例所示。

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

此运算符的等效方法是 Decimal.Compare(Decimal, Decimal)
