Some of the reduction operations may be standardized with the correct rounding requirement in the future IEEE 1788 standard on interval arithmetic (even though I think that such operations do not belong to IEEE 1788), if it passes. In any case, they should also have their own correctly rounded version. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
