Single.MinValue Single.MinValue Single.MinValue Single.MinValue Field

定義

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

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

フィールド値

定数をMinValue示すコード例を次に示します。The following code example demonstrates the MinValue constant.

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

注釈

この定数の値は、負の 3.402823 e38 です。The value of this constant is negative 3.402823e38.

よりSingle.MinValue小さい演算の結果がSingle.NegativeInfinityです。The result of an operation that is less than Single.MinValue is Single.NegativeInfinity. 次の例ではSingle.NegativeInfinity 、結果がよりSingle.MinValue小さい場合、減算および乗算演算の結果が返されます。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)
