This is test suite issue caused by the changes in float formating in Python 
3.2. I'm working on a new release and I'll try to find a way to change the test 
suite. If you are looking for properly rounded floating point arithmetic, the 
SVN version of gmpy2 supports the MPFR and MPC libraries and they much better 
floating point support.

I've released 1.15 which fixes the formatting issues in the tests.
