The field of numerical analysis predates the invention of modern computers
(and hence CS) by many centuries. It's true that Numerical Analysis deals
w/ more than just binary representation of real numbers, but it *does* deal
w/ them.

Speaking from my experience, I know more Mathematicians who understand how
floating point numbers work than I do computer scientists who know, and I
probably know 10 computer scientists for each mathematician that I know. I
am always dismayed by how many computer scientists don't really know
anything about floating point numbers, other than the obvious. This may be
related to more Math departments requiring a numerical analysis class than
CS departments, but I don't really know.

Take that for whatever it's worth. Your experience may be very different
from mine.
