I don't like either of these solutions.
How do others deal with this?

Short answer: floating point numbers suck, but are fast. If you need
accuracy you should convert your numbers into integers (for instance,
financial programs tend to use fractions of a penny, so 1000 is one
cent) or move to a slower but exact math system like
[Math::Currency][0] (note, this is not an endorsement of that module,
I have never used it).

Thanks... that's the sort of answer I've been reading about... not crazy
about it... but it is what it is. This problem is more infuriating than
unsolvable in terms of why I need to even think about something like
this. My $0.99 calculator can computer those numbers precisely, but my
$3000 server can't.
