Duh, I got the < and <= bug! Shows how easy it is to get this kind of
function wrong. (Even more so, it shows how easy it is to get code
wrong when you type straight into an email and never test it.)

Yeah, and that's the problem. If you're working with some concept of
measurement error, what you actually mean is that every number in your
calculation is actually a range centered on that number; which means
that "equality" really means "overlapping ranges". Epsilon-based
equality is just that, only with a global epsilon instead of one that
actually cares about the real error value. How can that NOT be doomed
to failure?
