Well, if nothing else, I'm certainly satisfied that my concerns about accuracy are being addressed. I will have to go read more of that discussion. > I prefer having > float not implement Rational (Decimal's off the table) because > developers usually think of them as approximations to arbitrary, > possibly-irrational, real numbers, rather than as rational numbers > with some odd constraints on their denominators.

My personal stance is that developers _shouldn't_ think that way, but I know that's an unpopular opinion, and isn't really worth discussion here. > [ A new thread is probably appropriate if anyone wants to discuss the > philosophy, but I probably won't participate... ] I don't feel any pressing need to continue this here and now.
