Nice work, Mark.

sqrt(a/b) should always be equal to sqrt(a)/sqrt(b) since (a/b)^m =
a^m/b^m for b != 0. However, I'm unsure of whether it's the best
option for ratios because unless both the numerator and the
denominator are perfect squares, you're going to end up with a float
anyway. This is trading an extra s

Ideally I'd also like that, but since complex numbers aren't part of

Floating-point numbers are exact -- it's their operations that may not
be. *ducks*
Seriously, handy code -- many thanks! I should check with someone
whether sqrt(a/b) -> sqrt(a)/sqrt(b)
