[PYTHON MATRIX-SIG] FW: Arbitrary precision numbers!

[Tim Peters]

Lest it escape your number-crunching attentions, please note that Jurjen N.E. 
Bos posted a terrific "infinite precision" real-number library to 
comp.lang.python on Friday, under subject "Arbitrary precision numbers" 
(sorry, I got this off the Python mailing list, so can't supply a proper 
newsgroup reference).  I'll attach the short teaser from the start; the whole 
msg also contains a very clear "user manual" and complete & self-contained 
Python source.

The start of Jurjen's msg:

Hi folks:
I just wrote a module "real.py" that allows to do computations with
arbitrary precision numbers. For details, see the file "real.doc" below.
Just to whet your appetite:
>>> from real import pa,exp,pi,sqrt
>>> pa('exp(pi()*sqrt(163))')
