Code, yes--  its just not ready to be seen by the light of day.  It has
taken a long time because I want to make it possible for CPython and Jython
to eventually have the same FP semantics -- or at least as close as
possible.  I've yet to directly tackle the direct Python implementation, but
I'm working on a C library I'm calling libieee754 that abstracts the bulk of
what C99 FP allows, even though most platforms do not yet support it
directly.  My goal is for a public release in the next few months, a formal
PEP and Python integration soon thereafter.
