Python 2.4's decimal module is, in essence, a floating point emulator based on
the General Decimal Arithmetic specification.
If you want floating point mathematics that doesn't have insane platform
dependent behaviour, the decimal module is the recommended approach. By the
time Python 2.6 rolls around, we will hopefully have an optimized version
implemented in C (that's being worked on already).
That said, I'm not clear on exactly what changes you'd like to make to the
binary floating point type, so I don't know if I think they're a good idea or
not :)
Regards,
Nick.
