cr-libm, a portable, efficient, correctly rounded mathematical library. To compile: ./configure; make; (for options see ./configure --help) To run the selftest: make check; Beta release note: This version contains one state-of-the-art implementation. The log comes in two versions, log-td (portable) and log-de (optimised for processors with double-extended hardware). The ./configure should enable the one that is best for your system, except on Itanium: see below. There is no known bug, but several shortcomings are listed in the TODO file. Note for Itanium systems: Out-of-the box it should compile and selftest on Linux under both gcc and icc (feedback on HPUX is welcome). However, optimised versions of log and atan are disabled. They currently require icc 8.1 or later. See the beginning of log-de.c and atan-itanium.c for instructions on how to enable them.
