Go ahead. istm that asking modulo, trunc, etc to Do The Right Thing is not a big deal, and it would be better to understand how to build executables that can do math. Certainly better than writing a bunch of extra checking code to work around the inability of a compiler (or compiler options) to do IEEE math. It *is* a standard, ya know ;) - Thomas ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
