Hi Audrey!
I think that you are confusing rounding with formatting. What is
displayed depends upon the formatting that you have applied, or in the
case of General format, is based upon the column width and font size
used. In all these cases, your formula is being stored in Excel as
calculated.
So rather than change your formula, increase the column width or
select a format you feel is accurate enough for display purposes. But
remember that neither action is changing the stored answer.
