Public Const MinValue As Double

Field Value

Type: System.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)
