# Single.MaxValueSingle.MaxValueSingle.MaxValueSingle.MaxValue Field

## 定義

Single の最大有効値を表します。Represents the largest possible value of Single. このフィールドは定数です。This field is constant.

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

## 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
``````

## 注釈

この定数の値は、正の 3.40282347 E + 38 です。The value of this constant is positive 3.40282347E+38.

を超えるSingle.MaxValue演算の結果はSingle.PositiveInfinityです。The result of an operation that exceeds Single.MaxValue is Single.PositiveInfinity. 次の例ではSingle.PositiveInfinity 、結果がを超えSingle.MaxValueた場合の加算、乗算、および指数演算の結果を示しています。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)
``````
