Single.MinValue Field

Definition

Namespace:

System

Assembly:

System.Runtime.dll

Source:

Single.cs

Represents the smallest possible value of Single. This field is constant.

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

Field Value

Value = -3.40282347E+38

Single

Examples

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
    printfn "Your number is smaller than a Single."

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

Remarks

The value of this constant is negative 3.402823e38.

The result of an operation that is less than Single.MinValue is Single.NegativeInfinity. 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)

open System

let result1 = -8.997e37f + -2.985e38f       
printfn $"{result1} (Negative Infinity: {Single.IsNegativeInfinity result1})" 
      
let result2 = -1.5935e25f * 7.948e32f
printfn $"{result2} (Negative Infinity: {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)
