Single.MinValue 字段

定义

命名空间:

System

程序集:

System.Runtime.dll

Source:

Single.cs

表示 Single 的最小可能值。 此字段为常数。

public: float MinValue = -3.40282347E+38;

public const float MinValue = -3.40282347E+38;

val mutable MinValue : single

Public Const MinValue As Single  = -3.40282347E+38

字段值

Value = -3.40282347E+38

Single

示例

下面的代码示例演示 常 MinValue 量。

if ( s < Single::MinValue )
{
   Console::WriteLine( "Your number is smaller than a Single." );
}

if (s < Single.MinValue)
{
    Console.WriteLine("Your number is smaller than a Single.");
}

if s < Single.MinValue then
    printfn "Your number is smaller than a Single."

If S < Single.MinValue Then
    Console.WriteLine("Your number is smaller than a Single.")
End If

注解

此常量的值为负 3.402823e38。

小于 Single.MinValue 的操作的结果为 Single.NegativeInfinity。 在以下示例中， Single.NegativeInfinity 当结果小于 Single.MinValue时，减法和乘法运算的结果。

using System;

public class Example
{
   public static void Main()
   {
      float result1 = -8.997e37f + -2.985e38f;       
      Console.WriteLine("{0} (Negative Infinity: {1})", 
                        result1, Single.IsNegativeInfinity(result1));
      
      float result2 = -1.5935e25f * 7.948e32f;
      Console.WriteLine("{0} (Negative Infinity: {1})", 
                        result2, Single.IsNegativeInfinity(result2));
   }
}
// The example displays the following output:
//    -Infinity (Negative Infinity: True)
//    -Infinity (Negative Infinity: True)

open System

let result1 = -8.997e37f + -2.985e38f       
printfn $"{result1} (Negative Infinity: {Single.IsNegativeInfinity result1})" 
      
let result2 = -1.5935e25f * 7.948e32f
printfn $"{result2} (Negative Infinity: {Single.IsNegativeInfinity result2})" 
// The example displays the following output:
//    -Infinity (Negative Infinity: True)
//    -Infinity (Negative Infinity: True)

Module Example
   Public Sub Main()
      Dim result1 As Single = -8.997e37 + -2.985e38
      Console.WriteLine("{0} (Negative Infinity: {1})", 
                        result1, Single.IsNegativeInfinity(result1))
      
      Dim result2 As Single = -1.5935e250 * 7.948e110
      Console.WriteLine("{0} (Negative Infinity: {1})", 
                        result2, Single.IsNegativeInfinity(result2))
   End Sub
End Module
' The example displays the following output:
'    -Infinity (Negative Infinity: True)
'    -Infinity (Negative Infinity: True)
