By "enable FP exceptions", I think you mean set a trap for these exceptions (documents often mix "exception" and "trap"). But there doesn't seem to be standard support for traps in C. The Glibc provides feenableexcept, fedisableexcept and fegetexcept functions for that. -- 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)
