[Python-Dev] Re: PEP239 (Rational Numbers) Reference Implementation and new issues

[Guido van Rossum]

After reading most of the discussion, I don't know what to do about
this.  There are a number of different ideas that should be reviewed
separately: "classic" rationals, fixed-point decimal, a new kind of
floats with settable precision...

I tend to think that rationals and superfloats are sufficiently
esoteric that they should probably be relegated to an extension or
library module.  Fixed-point decimals have some nice properties, but
apparently implementing it isn't easy -- Aahz has been sitting on a
prototype approximately forever.  I hear that Tim's FixedPoint package
is now a SF project.
