Hi Ed,
I have to accept that the TR1 math won't be done for 4.2. However, I
have enough done that I think it would be worthwhile to report on the
status and get some feedback and suggestions and maybe some help.
I'm looking into the patch draft. A few immediate, rather obvious
comments for the next iteration.
A couple of additional sparse comments:
10- M_PI is a *double* constant, as such not suited for long double
computations (the glibc math.h header is pretty clear about that)
11- At this point, certainly I'm not going to discuss the merit of each
specific algorithm (maybe a little bit after some bibliographic
citations...), but it seems to me that all those replicated __max_iter
cannot be the final solution: at minimum the specific values should be
discussed a bit and changed to commonized macros, I think.
Paolo.
