number
The number to validate.
Returns true if the specified number is a valid number; converts numbers suffering from underflow to +0.0; returns false if the number cannot be validated.

Syntax

C# 
virtual bool ValidateNumber( 
   ref double number
)

Parameters

number
The number to validate.

Return Value

true if the number is valid, false otherwise.

Remarks

Unlike Value, SetNumber assumes the number being placed in a cell is a valid number. A valid number is either +0.0, or a non-zero number which is not suffering from underflow or overflow. If number is suffering from underflow or is equal to -0.0, it will be set to +0.0 and true will be returned. If the number cannot be validated, false is returned.
