Now that this mailing list has been created, let me just provide a link to PR bin/170206 http://www.freebsd.org/cgi/query-pr.cgi?pr=170206 Two main threads to this discussion: 1. I am submitting complex arc-trig and complex arc-hyperbolic functions casin, cacos, catan, casinh, cacosh, catanh. 2. The main difficulty in trying to implement clog is computing it's real part: log(|z|) = 0.5*log(x^2 + y^2) when |z| is very close to 1. It is very hard to get a reasonably low relative error. I hope these discussions, as well as many other, move to this mailing list. Stephen
