Excel has a help facility which explains each function (except DATEDIF), and
its syntax, and gives examples. You can either get at it through the help
window, or through the help menu, or by clicking on the hyperlink which
appears if you click on the function name in the formula, or by clicking on
the "fx" to the left of the formula window.

I have a formula in a workbook and I don't know what it means. Can you
please
tell me what ROUND means and also the ,5 at the end of the formula?

=ROUND((Z13-AB13),5)


Thanks!
