virtual 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.
