Formulas computed from currency cells always yield a currency-formatted value. Attempts to change the formatting of the cell to "number" fail. For instance, I was attempting to compute the percent increase in the value of an investment over a period. A1 = 01/01/2013 B1 = $1000 A2 = 02/03/2013 B2 = $1003 then let C2 have the formula "=(B2-B1)/(A2-A1)" the cell C2 ends up formatted as currency, when of course those units don't apply here. Hopefully I've narrowed it down to a reproducible scenario. I don't know whether the problem applies outside of just currency. Thanks for the amazing work you do!! :)
