字段值

示例

下面的代码示例演示 常 MaxValue 量。

if ( s > Single::MaxValue )
{
   Console::WriteLine( "Your number is larger than a Single." );
}

if (s > Single.MaxValue)
{
    Console.WriteLine("Your number is larger than a Single.");
}

if s > Single.MaxValue then
    printfn "Your number is larger than a Single."

If S > Single.MaxValue Then
    Console.WriteLine("Your number is larger than a Single.")
End If

注解

此常量的值为正 3.40282347E+38。

超出 Single.MaxValue 的操作的结果为 Single.PositiveInfinity。 在以下示例中， Single.PositiveInfinity 当结果超过 Single.MaxValue时，加法、乘法和指数运算的结果。

using System;

public class Example
{
   public static void Main()
   {
      float result1 = 1.867e38f + 2.385e38f;
      Console.WriteLine("{0} (Positive Infinity: {1})", 
                        result1, Single.IsPositiveInfinity(result1));
      
      float result2 = 1.5935e25f * 7.948e20f;
      Console.WriteLine("{0} (Positive Infinity: {1})", 
                        result2, Single.IsPositiveInfinity(result2));
   }
}
// The example displays the following output:
//    Infinity (Positive Infinity: True)
//    Infinity (Positive Infinity: True)

open System

let result1 = 1.867e38f + 2.385e38f
printfn $"{result1} (Positive Infinity: {Single.IsPositiveInfinity result1})" 
      
let result2 = 1.5935e25f * 7.948e20f
printfn $"{result2} (Positive Infinity: {Single.IsPositiveInfinity result2})" 
// The example displays the following output:
//    Infinity (Positive Infinity: True)
//    Infinity (Positive Infinity: True)

Module Example
   Public Sub Main()
      Dim result1 As Single = 1.867e38 + 2.385e38
      Console.WriteLine("{0} (Positive Infinity: {1})", 
                        result1, Single.IsPositiveInfinity(result1))
      
      Dim result2 As Single = 1.5935e25 * 7.948e20
      Console.WriteLine("{0} (Positive Infinity: {1})", 
                        result2, Single.IsPositiveInfinity(result2))
   End Sub
End Module
' The example displays the following output:
'    Infinity (Positive Infinity: True)
'    Infinity (Positive Infinity: True)
