I sure wouldn't <wink>.  Note that use of %f ends up calling
FixedPoint.__float__(), though, and so sucks users right back into binary fp
surprises:

>>> t = FixedPoint.FixedPoint(".1")
>>> print t
0.10
>>> print "%.17f" % t
0.10000000000000001
>>> float(t) == 0.1
True
>>>

FixedPoint does the best possible job of converting 1/10 to a float, but
it's exactly as surprising as the float literal 0.1 then.
