I found this article more useful, interesting, and informative than
whatever I learned about binary floating-point in my academic years.
Good link, Tim. Two catches:
* I can just barely follow the FORTRAN examples; I very much doubt
the average Python newbie would have any more luck than me
* I tried several of the FORTRAN examples in Python, and did not
witness any of the gotchas they are meant to illustrate. Possibly
it's just single-precision vs. double-precision difference, but
Python 2.1 under Linux 2.2 on an Athlon compiled with gcc 2.95.2
doesn't demonstrate the same gotchas as that article does.
