FYI: a draft set of C bindings for additional floating-point functions from IEEE 754-2008 are now available (draft TS 18661-4):
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1785.pdf This is in addition to the previous three draft parts of bindings to IEEE 754-2008, part 1 (binary arithmetic), part 2 (decimal arithmetic) and part 3 (interchange and extended types). Part 5 (supplementary attributes, e.g. alternate exception handling) is not yet available. http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1778.pdf (part 1) http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1781.pdf (part 2) http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1784.pdf (part 3) Any issues with these draft bindings would best be reported directly to WG14 (sc22w...@open-std.org). Parts 1 and 2 are in ballot, parts 3 and 4 are at earlier stages of development. -- Joseph S. Myers jos...@codesourcery.com
