Hi
my python 2.3.4 for windows refuse to execute line float(NaN). It
says:
float(NaN)
Traceback (most recent call last):
File stdin, line 1, in ?
ValueError: invalid literal for float(): NaN
The same line works as expected on Linux and Solaris with python 2.3.4.
Could anybody explain what is

C99 and Fortran 2003 have IEEE arithmetic. If CPython could be compiled
with a C99 compiler, would it also have IEEE arithmetic? Do Python

Not that simple (e.g., C99 doesn't *require* it; but it has a pile of
specified IEEE behaviors a conforming C99 compiler can choose to
support (or not), along with a preprocessor symbol those that do so
choose can #define to advertise
