However (if this is the change I'm thinking of) this makes math functions "correct" in directed rounding modes and potentially more secure. By "correct", I mean that the result is somewhat acceptable (not that the result is correctly rounded and the rounding direction is honored), instead of getting completely wrong values or even a crash. -- 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) -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
