Ah.  Okay, but then what's wrong with the original proposal of "use ceil()
instead of floor()"?  Basically I think the idea of treating fractions
less than one differently from fractions greater than one is bogus; nobody
will ever find that intuitive.

Or we could adopt Peter's idea that zero shouldn't be special (instead
using, say, -1 to turn things off).  But I'm afraid that would break way
too many peoples' configuration choices.
