Until you try running your program on a machine that represents floats
using a radix other than 2,4, or 16.

And it works for NaN and Inf too!

It would have been nice to have had that 5-6 years ago when I had to
write my own pickle/unpickle methods for floating point values so that
inf and nan were portable between Windows and Linux.
