Hi -

I'm curious if there is any interest in the Python community to achieve 
better cross-platform math behavior. A quick test[1] shows a 
non-surprising difference between the platform implementations. 
Question: Is there any interest in changing the behavior to produce 
identical results across platforms (for example by utilizing fdlibm 
[2])? Since I have need for a set of cross-platform math functions I'll 
probably start with a math-compatible fdlibm module (unless somebody has 
done that already ;-)

Cheers,
   - Andreas
