Terry, I just noticed that farey(0.36, 10) returns (1, 3), a pretty big miss, IMO. The correct fraction with smallest error and maximum denominator of 10 is 3/8, which I'm proud to say my klunky frac.py (<http://www.rcblue.com/Python/fracForWeb.py>) produces. Be that as it may, farey() is an amazing program. I appreciate the fast replies from you and Danny to my plea for explication. I'm still working through them.
