Surely you meant 'rat(3, 5)'. :-)

I'd like at least one of those return '0.6' or '0.6r'.  I think str(r)
should return '0.6', and then repr(r) could return '3/5r'.  For values
that require approximation as decimal, I'd say use the same number of
digits that str() of a float currently uses (about 12 I believe).  So
str(1/3r) should be '0.333333333333'.
