[REBOL] Re: financial functions

From: chalz:earthlink at: 17-Apr-2002 13:27

Heh! Perhaps if I had some idea as to what internal rate of return meant, I could give you a hand ;) Perhaps the difference between your function and Excel's function is a matter of rounding? Since I see no decimals in your comparative values, and they are so close, it almost seems to suggest that you rounded up, where Excel rounded down No?
