By searching with grep, I can't see any NaN-generating code
in either the Python or its Numerical Extension.
GSL-0.6 defines it from NAN macro or (0.0/0.0),
but they will "sort out" it, according to their TODO.

IMHO, A practical way is, to check IEEE 754 support at the
configure time, and then define Float::NAN with 0.0/0.0 or
the bit pattern of NaN.
