Hey guys, I just found this paper: Implementing complex elementary functions using exception handling, T. E. Hull, Thomas F. Fairgrieve, Ping-Tak Peter Tang ACM Transactions on Mathematical Software, Volume 20 Issue 2, June 1994 Pages 215-244 http://dl.acm.org/citation.cfm?doid=178365.178404 This includes an algorithm for clog. Now that I have discovered just how hard it really is, I am going to read this paper. There is also a Corrigenda to this paper - the digital copy seems to be missing. But I will try to retrieve the paper copy from my library. http://toms.acm.org/cgi/TOMSbibget.cgi?Anonymous:1994:C If anyone else wants a copy of these papers, I would be glad to share it. But I am using the University of Missouri subscription to ACM, and I don't want to abuse it by sharing the paper willy-nilly.
