Comment #6 on issue 3446 by asmeu...@gmail.com: interactions with Float(0.0)
http://code.google.com/p/sympy/issues/detail?id=3446
WFIW, I think we should try to fix this somehow (or at least do a better
job of convincing ourselves that fixing it is impossible). Float(0) -> 0
is very inconsistant. Can't we just fix the core to either check for 0.0
for cancelation, or else to make 1.0*x - 1.0*x give 0.0*x instead of 0?
