FixedPoint release 0.1.1
What it is
This package encapsulates the representation of a fixed point number in
Python. It was originally written by Tim Peters and posted to the Python
What it does
The FixedPoint object supports all suitable Python operators to enable the developer
to perform fixed point math in a natural way.
This is a (hasty) bugfix release for 0.1.0
We discovered that my alternative rounding algorithm didn't behave
correctly for negative quotients.
Tim, the original author recommended making _roundQuotient a member of
FixedPoint, enabling the rounding algorithm to become a normal member,
rather than a static member.
While refactoring, I changed the name from 'RoundingAlgorithm'
to the less verbose 'round'.
So instead of
from fixedpoint import FixedPoint, BankersRounding
FixedPoint.RoundingAlgorithm = staticmember(BankersRounding)
you can say
from fixedpoint import FixedPoint, bankersRounding
FixedPoint.round = bankersRounding
We got a good description of rounding philosphy from Tim in an email.
Joe has incorporated this in the documentation.

This release (really truly) concludes our planned changes to FixedPoint.
We're going to sit back and watch for bug reports and feature
requests, but we won't mess with the code anymore without
