Decimal places in linked cells

Hi,

Assume I have a formula in Cell A1 and this is linked to Cell A2 so that A2=A1. If the result of the formula is not a whole number then the number of numerals after the decimal are variable. Is there a way to standardize this (e.g. 00.00) without using vba? I know that you can do this cosmetically by using the cell formatting options, but is there a way for the actual number in linked cell to be the number of decimal places I need?

Thanks in advance.
