At a quick glance, I'd say you're violating my copyright in the most blatant and irresponsible manner. If the infringing stuff isn't off the internet in short order, I will be taking legal action.
If we're going to do a 99.44%-standard-C math.h implementation, it would probably make more sense to start with the sun (bsd-licensed) math library, and convert it to not use bit-patterns to deal with IEEE 754. --Random832 23:20, 11 March 2006 (GMT)
In the header file, I took out everything that Plauger would have a beef about. Some of the other files look like Plauger's implementations, which is what I was worrying about.
The problem with some of the "free" math libraries out there like fdlibm is that they only provide functionality for C90 and/or don't handle extreme cases in a responsible manner like Plauger's library, so I was trying for a balance. Gregory Pietsch 01:44, 12 March 2006 (GMT)
