That is tautological. Programs NOT written with IEEE arithmetic in mind may very well produce undetected nonsense (instead of silly but detectable behavior, like a core dump). The whole IEEE arithmetic approach has both proponents and opponents, reasonable people all, and this is not the place to argue its merits. I'm glad to see that at least SOME indication that exceptions were triggered is available under the latest Sun Fortran. P.S. Thanks to D. Hough for his help in improving the ANSI C floating-point specs.
