I suggest using PEP 327 as a starting point, though. A few of the issues
Cowlishaw talks about in the General Decimal Arithmetic spec are specific to
hardware implementations, sure, but it doesn't appear to involve anything
numerically insane (granted, they've added exp, ln and log10 to the spec since
PEP 327 was implemented. . .).
The only downside I know of when it comes to trying to do serious number
crunching with the current decimal implementation is the loss of raw speed
relative to hardware floating point, and Mateusz is working on improving that
situation.
Cheers,
Nick.
