Component: multiprecision → geometry
Owner: changed from John Maddock to Barend Gehrels

This looks like a Geometry traits class question not a multiprecision one?

BTW I'm not sure if this is relevant, but mpq_rational is static_cast'able to double in C++11 land. It rounds correctly as well which mpq_get_d appears not to.
