Thanks for keeping me honest. I'll definitely improve this before I push anything. I don't have a good list of platforms on which isnan is missing, because Bruno's list by platform only covers functions, but I can do better than what is given here. I can come up with some platforms that have incorrect results by merging the docs for isnanf and isnanl. -- Ben Pfaff http://benpfaff.org
