The objectives were to bring the functions into strict ANSI compliance and improve the accuracy of the routines, while maintaining the speed of the existing libc routines. The new routines are not quite finished yet, but I have coded all of them except pow(), and in accuracy tests against some 384-bit reference routines that I downloaded from the Web, they have so far been flawless (apart from range reduction being good only to 64 bits). I have been in correspondence with Eli Zaretskii about this effort, and he suggested that I post this message. I would appreciate any suggestions that you may have about putting the package together and submitting it. Eli also mentioned that there was a new test suite in the 2.02 alpha release, so will download it and test my routines against that suite, in addition to the other tests I have already run. -Eric Rudd rudd AT cyberoptics DOT com
