Understood. Thank you!

This was a "demonstration problem" - my actual application will involve
arbitrary-precision reals with lots of constraints.
It appears that PPL not only supports rationals, but insists on them. It
seems to set the base_ring to QQ, as the output from the following code is
"Rational Field", but

Thanks for your answer. Though I have defined and now use such a function
you suggested, but I need to calculate this function later for thousands
of different inputs. This means a huge amount of computation that can be
avoided, by once deriving an expression in terms of x[i]'s and then just
r
