Single.MinValue フィールド

定義

Single の最小有効値を表します。 このフィールドは定数です。

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

フィールド値

Value = -3.40282347E+38

次のコード例は、 定数を MinValue 示しています。

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
    printfn "Your number is smaller than a Single."
If S < Single.MinValue Then
    Console.WriteLine("Your number is smaller than a Single.")
End If

注釈

この定数の値は負の 3.402823e38 です。

より Single.MinValue 小さい操作の結果は です Single.NegativeInfinity。 次の例では、 Single.NegativeInfinity 結果が より Single.MinValue小さい場合、減算演算と乗算演算の結果が得られます。

{
   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)

let result2 = -1.5935e25f * 7.948e32f

// The example displays the following output:
