> Thanks, Maldun, this is a good addition to have. I don't have time to
review this immediately, but it would be helpful to know if you detected
any errors, compared this with symbolic integrals and their evaluation,
etc. Basically, that the results from this really are as accurate as
advertised.

patch you posted above, or even as an optional argument, though that may
not be compatible with `_evalf_` elsewhere...
I will consider this, but hopefully it is not necessary, and mpmath will
do the whole thing.
If I understood that right, burcin wants to change the numerical
evaluation completly to mpmath, because it supports arbitrary prescision.
I plyed arround a little, and I didn't find any differences between the
other evaluation methods. In some cases it works even better (I had an
example recently in ask sage, which motivated me to switch to this form ov
_evalf_)
