SpreadsheetGear.Advanced.Cells Namespace > IValues Interface : IsValidNumber Method

number
The number to validate.
Returns true if the specified number is a valid cell number, otherwise false is returned.

Syntax

Visual Basic (Declaration) 
Function IsValidNumber( _
   ByVal number As Double _
) As Boolean
C# 
bool IsValidNumber( 
   double number
)

Parameters

number
The number to validate.

Return Value

true if the number is a valid cell number, false otherwise.

Remarks

Unlike Value, SetNumber assumes the number being placed in a cell is a valid cell number. A valid cell number is either zero, or a non-zero number which is not suffering from underflow or overflow. Positive infinity, negative infinity and NaN are not valid cell numbers.

Platforms: Windows 2000, Windows XP, Windows Vista, Windows Server 2003 and Windows Server 2008. SpreadsheetGear 2009 requires the Microsoft .NET Framework 2.0 and supports .NET 3.0 and .NET 3.5.
