Excel has a limit of 15 digits. If your are working with really big
umbers - meaning you want to do arithmetic operations on these numbers -
then Excel is not for you. But if they are nor true numbers (ie things like
credit card numbers) then they can be entered as text by
1) first formatting the cell as Text
OT 2) typing a single apostrophe before the 'number' - the apostrophe will
not display in the cell, nor will it appear in a print out.
