Possible misunderstanding: I mean a rational function in the sense of Padé approximation or CF [1], not just representing individual numbers as p/q.
I did not find anything related to this in Sollya [2].

- janwas 2y agoThanks! Yes, that (rminimax/ratapprox) looks very interesting. I got the impression that this was separate from Sollya. Fair point about the correct rounding. We'd be fine with several ULPs.
