'Declaration
 
Public Shared Function GetFractionDigits( _
   ByVal value As Double, _
   ByVal allowExponentialFormat As Boolean, _
   ByRef exponentialFormat As Boolean _
) As Integer

'Usage
 
Dim value As Double
Dim allowExponentialFormat As Boolean
Dim exponentialFormat As Boolean
Dim value As Integer
 
value = UIHelper.GetFractionDigits(value, allowExponentialFormat, exponentialFormat)

public static int GetFractionDigits( 
   double value,
   bool allowExponentialFormat,
   out bool exponentialFormat
)

Parameters

value: The numeric value.
allowExponentialFormat: true if the exponential format is allowed; otherwise, false.
exponentialFormat: A boolean value indicates whether the exponential format is used. This value is used only if allowExponentialFormat is true.

Return Value

-1 if the value is not a number.
