But contrary to invalid operations (and overflows, at least in rounding to nearest), the only way to detect it is to test the exception status flags; the numerical value won't say anything about the exception (unless you have some knowledge about it, such as you know that the value is an integer but you don't get an integer... But not all inexact exceptions can be detected in such a way). -- Vincent Lefèvre <vincent@xxxxxxxxxx> - 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)
