There are several things wrong with this reasoning, but pragmatically the conclusion may be right: we do have a long list of users who would prefer a dubious implementation to none at all. I propose we set a timeframe for this, on the order of a few months. A rough outline might be something like: mid-August: expl logl log2l log10l -- just need to clean up Bruce and Steve's work; Steve recently sent me patches for expl, which I hope get committed soon mid-September: acoshl asinhl atanhl coshl sinhl tanhl -- easy once expl is in; others could probably help mid-October: powl expm1l mid-November: most complex.h functions If the schedule can't be met, then we can just import Cephes as an interim solution without further ado. This provides Bruce and Steve an opportunity to commit what they have been working on, without forcing the rest of the FreeBSD community to wait indefinitely for the pie in the sky. By the way, the trig and complex functions are areas where anyone with some calculus background could contribute. If anyone is interested in helping out, I'd be happy to coordinate things and review patches, although I will be unavailable for much of August.Received on Fri Jul 13 2012 - 13:58:13 UTC
