Title: No evalf 1

Don't use `n(1)` or `evalf(1)`. See [issue 3235](http://code.google.com/p/sympy/issues/detail?id=3235) (which this fixes) for more information.

I'd like a verification from someone familiar with the core code I've modified that this is correct.

Also, can someone look at the change in the printing test. Is that right? Is this a consistant value (i.e., something we should be testing)?
