# Single.MinValue 字段

## 定义

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

## 示例

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

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)
