This may be a dumb question, but is there any particular
There is a post on boost (http://boost.org) about floating point utilities
that are being considered for review. This seems to have a lot of overlap
with python needs. I haven't reviewed this myself, but boost code is meant
to be quite portable. Here is the link:

Dear all,
I'd like to draw your attention to some of the work that's been going on in
the trunk-math branch. Christian Heimes and I have been working on various
aspects of Python mathematics, and we're hoping to get at least some of this
work into Python 2.6/3.0. Most of the changes are
