Comment #2 on issue 3736 by [email protected]: big numbers fail
http://code.google.com/p/sympy/issues/detail?id=3736
You know what, I get that now, too. I tried it on a system with very low
memory and was able to recreate the error I got above, so I think maybe
when I ran the above, I had a lot of other processes running taking up lots
of memory.
As for how to fix it, maybe report it upstream and hope that someone else
will take care of it :) After all, in a regular python session, without
sympy imported, I get:
import mpmath
mpmath.exp(mpmath.exp(mpmath.exp(mpmath.exp(7.705))))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/pymodules/python2.7/mpmath/ctx_mp_python.py", line 993, in
f
return ctx.make_mpf(mpf_f(x._mpf_, prec, rounding))
File "/usr/lib/pymodules/python2.7/mpmath/libmp/libelefun.py", line 1173,
in mpf_exp
t = man << offset
ValueError: outrageous shift count
I'm not sure if it's something they want to fix. In that case, we could
look into alternatives.
