"Scary Math" Solver

[Dave Brueck]

Sorry if somebody already point this out but...

If it shakes your faith to know that many floating point numbers can't be
stored without slight rounding errors, in Python 2.1 you can always do this
to change how things work in interactive mode:

>>> 5.3
5.2999999999999998 # HELP! SAVE ME!!!
>>> def printstr(s):
>>>    print str(s)
>>> import sys
>>> sys.displayhook = printstr
>>> 5.3
5.3   # I BELIEVE!!!

And you could modify printstr so that other data types still use repr.
