Comment #8 on issue 3235 by asmeu...@gmail.com: Sage error in master
http://code.google.com/p/sympy/issues/detail?id=3235
Ah, well it's the simple fact that it's using Sage's mpf_log instead of the
one in the sympy mpmath.
The evalf(1) indeed comes from that commit I mentioned above. I guess it
was done to give the smallest possible value. I don't understand why
sage's mpmath requires a precision of 2 or greater, but sympy's doesn't.
Fredrik, maybe you could shed some light on this?
Anyway, it should be easy enough to change. Chris, do you know of other
instances where a precision of 1 is used?
