Not by changing the rounding precision. Anyway this is not the point here (i.e. to consider where the bug comes from). > 4) cause some algorithms that work now to fail Only non-portable ones (those designed for extended precision only). And portable algorithms that didn't work will work after the fix. -- Vincent Lefèvre <[EMAIL PROTECTED]> - Web: <http://www.vinc17.org/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.org/blog/> Work: CR INRIA - computer arithmetic / SPACES project at LORIA
