Double.MinValue Field

Represents the smallest possible value of a Double. This field is constant.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Public Const MinValue As Double

The value of this constant is negative 1.7976931348623157E+308.

The result of an operation that is less than Double.MinValue is Double.NegativeInfinity. In the following example, Double.NegativeInfinity results from subtraction and multiplication operations when the result is less than Double.MinValue.

Module Example
   Public Sub Main()
      Dim result1 As Double = -7.997e307 + -9.985e307
      Console.WriteLine("{0} (Negative Infinity: {1})", 
                        result1, Double.IsNegativeInfinity(result1))

      Dim result2 As Double = -1.5935e250 * 7.948e110
      Console.WriteLine("{0} (Negative Infinity: {1})", 
                        result2, Double.IsNegativeInfinity(result2))
   End Sub 
End Module 
' The example displays the following output: 
'    -Infinity (Negative Infinity: True) 
'    -Infinity (Negative Infinity: True)

The following code example illustrates the use of MinValue:

Public Class Temperature

    Public Shared ReadOnly Property MinValue() As Double 
            Return Double.MinValue
        End Get 
    End Property 

    Public Shared ReadOnly Property MaxValue() As Double 
            Return Double.MaxValue
        End Get 
    End Property 

    ' The value holder 
    Protected m_value As Double 

    Public Property Value() As Double 
            Return m_value
        End Get 
        Set(ByVal Value As Double)
            m_value = Value
        End Set 
    End Property 

    Public Property Celsius() As Double 
            Return (m_value - 32) / 1.8
        End Get 
        Set(ByVal Value As Double)
            m_value = Value * 1.8 + 32
        End Set 
    End Property 
End Class
