25318 Improve basic operations with fraction field elements mmezzarobba "As discussed in
[https://groups.google.com/d/topic/sage-devel/Sqt4N8eVq-o/discussion this 2018-06 sage-devel discussion],
this is part of an effort to improve fraction field elements,
and in particular rational fractions in several variables,
spread across four tickets:
- #25318: Improve basic operations with fraction field elements (the present ticket)
- #25290: Don't use Karatsuba for multiplying polynomials over fraction fields
- #23909; GCD for univariate polynomials over fraction fields
- #16268: Better normalization for fraction field elements
At least for some applications, these tickets bring Sage fraction field elements
from ""so slow they are unusable"" to ""not really great yet but reasonable"".
