I, personally, have not heard of this one yet. Maybe you mean 'Floor',
'Ceiling', 'Lower', or 'Upper'. Check the help menu for the details on
these. Maybe you are referring to a user defined function. If this is the
case you will have to provide a lot more details and, most likely, post your
question to the 'Excel Programming' discussion group.
Hope that helps.
