>This discussion confirms my impression, that it should be possible as an >interim solution, to use a port for missing math functions (cephes alike >or whatever). The port itself could warn the user about inaccuracies and >edge-cases. Parts of Cephes are already in ports: math/ldouble. I had planned to add the remainder. It can be useful, but it has problems, some of which have been described. The same is true of other open-source alternatives that I am aware of. >I would be happy to take on any steep learning curve, and make >contributions, if only I were part of a group that would steer me in the >right direction. A Functional Analyst offering to write code for a floating-point math library!?!! ;) You should send me a message off-list: maybe I can find some time to help. >Anyway, given that floating point is a big issue, and we are about a >decade behind schedule, really suggests that a >floating-point at freebsd.org mailing list is needed. Or maybe there is an >existing freebsd mailing list you guys already occupy. I do not know that a separate FreeBSD mailing list would be of great help, considering the likely volume of traffic, and the fact that we already have the standards mailing list. There is also: http://mailman.oakapple.net/pipermail/numeric-interest/ which serves, among other things, as a forum for discussing changes and improvements to the open-source math library from which parts of our system math library were derived: http://mailman.oakapple.net/pipermail/numeric-interest/2010-September/002054.html A wiki page detailing problems and procedures, with a wish list for the system libraries and toolchain(s) might help. At present there are only scattered messages in the mailing list archives, PRs, and http://wiki.freebsd.org/MissingMathStuff . b.Received on Thu May 31 2012 - 00:20:46 UTC
