Comment #10 on issue 3235 by vbraun.n...@gmail.com: Sage error in master http://code.google.com/p/sympy/issues/detail?id=3235
mpmath internally has different backends to do the computation. It uses mpir/mpfr if possible (i.e. if used from within Sage) and falls back to some python code otherwise (slow).
By the way mpfr.h has a #define MPFR_PREC_MIN that you would ideally use, though of course that isn't that easy to access from pure Python. From within Sage you can get it via
sage: from sage.rings.real_mpfr import mpfr_prec_min sage: mpfr_prec_min() 2 -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
