Single.MinValue 字段

定义

表示 Single 的最小可能值。Represents the smallest possible value of Single. 此字段为常数。This field is constant.

public: float MinValue = -3.402823E+38;
public const float MinValue = -3.402823E+38;
val mutable MinValue : single
Public Const MinValue As Single  = -3.402823E+38

字段值

示例

下面的代码示例演示 MinValue 常量。The following code example demonstrates the MinValue constant.

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
    Console.WriteLine("Your number is smaller than a Single.")
End If

注解

此常量的值为负 3.402823 e 38。The value of this constant is negative 3.402823e38.

Single.NegativeInfinity为小于 Single.MinValue 的操作的结果。The result of an operation that is less than Single.MinValue is Single.NegativeInfinity. 在下面的示例中,当结果小于 Single.MinValue时,Single.NegativeInfinity 减法运算和乘法运算结果。In the following example, Single.NegativeInfinity results from subtraction and multiplication operations when the result is less than Single.MinValue.

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)
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)
