Comment #19 on issue 1491 by asmeurer: Use nice ordering in printing
http://code.google.com/p/sympy/issues/detail?id=1491
If you change the default ordering to lex, a couple of the test failures
are outside of printing/, because they test the string of the expression.
These should be robustified, either by changing them to test the expression
itself, or in some other way.
There are a lot of failures in test_evalf.py because we get (with lex
ordering)
In [3]: 2 + 3*I
3⋅ⅈ + 2
and the tests test the string value of the output. This is kind of a less
than ideal order for numbers. Is there a way to modify the way that lex
works to make this print as 2 + 3*I without significantly redefining "lex"
(it should be possible--just special case I)?
