Okay, that makes sense. However, if I understand "wobbling precision" correctly (and it's a BIG if) then it refers to the fact that interpolating from the last digit of precision doesn't work so well (intentionally vague phrase). So I would think (but could be wrong) that it is always trumped by adding another digit of precision to your numbers / lookup tables / whatever. If so, then even more credit needs to be given to the system that supports adjustable precision (the Decimal module). -- Michael Chermside _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
