Python Power Series Power series representations in Python. Based on http://doc.cat-v.org/bell_labs/squinting_at_power_series/squint.pdf. This is a Python implementation of the pseudocode in the above paper by Doug McIlroy. Back when the paper was first written, McIlroy noted that languages with the key features needed for such an implementation were not in common use. Things are certainly different now; the Python implementation given here is a fairly straightforward expression of the algorithms in the paper, and it's fast, but McIlroy put a Haskell implementation on the web in 2007 that's way more compact; see here: http://www.cs.dartmouth.edu/~doug/powser.html All of the Haskell definitions there are one-liners. But I like Python, and AFAIK no one has done an implementation of this stuff in Python, so there you are. :-) See the docstring in powerseries.py for more information.
