Comment #11 on issue 895 by glenn.hortonsmith: series method does not work
if the point is not 0
http://code.google.com/p/sympy/issues/detail?id=895
OK, this patch has the exceptions raised in Basic.lseries() and
Basic.nseries(), and
uses S.Zero for the comparison. (And the patch file should be all there
this time,
I hope.)
With this patch, sympy/series/tests/test_nseries.py had three "failures"
due to
exceptions. One of them seems to have always been a bug in the test itself
(not
calling series correctly), while the other two tests were indeed testing
for correct
expansion of "ceil" and "floor" about a non-zero point, which now throws an
exception. The second attached patch fixes those tests, and also adds a
test for
the exception-throwing.
I hope this helps. I unfortunately won't have much more time to work on
this for a
couple weeks...
