He may someday commit it. I don't know if anyone ever worked on cpow[fl]. I stopped working on powl and tgammal when I returned my commit bit due to differences with "higher-ranking" committers. > And what had stopped the developers from just reusing the Net-i > or OpenBSD code? How have you tested the NetBSD and/or OpenBSD code? What is the quality? Have the long double clogl and cpowl been tested on both ld80 and ld128 hardware? See FreeBSD's lib/msun/src/math_private.h for a discussion of possible issues of using I from complex.h in this code. > Far as I see, FreeBSD's msun source resembles those other libm's a > lot anyway? Well, of course, the various libm's look alike. They all started life from Sun Microsystems fdlibm code. You can get the last release from Netlib. http://www.netlib.org/fdlibm/index.html -- Steve
