# Single.MaxValue 欄位

## 定義

``public: float MaxValue = 3.40282347E+38;``
``public const float MaxValue = 3.40282347E+38;``
``val mutable MaxValue : single``
``Public Const MaxValue As Single  = 3.40282347E+38``

## 範例

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

## 備註

The result of an operation that exceeds Single.MaxValue is Single.PositiveInfinity. 在下列範例中，當結果超出 Single.MaxValue時，Single.PositiveInfinity 加、乘和乘冪運算的結果。In the following example, Single.PositiveInfinity results from addition, multiplication, and exponentiation operations when the result exceeds Single.MaxValue.

``````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)
``````
``````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)
