I happen to get the correct answers out to 20! but only because I'm on 64bit hardware. The real issue is that the C standards specifies integer overflow as undefined behavior. Supposedly, with the proper flags, you can get gcc to give you a SIGFPE on signed overflow. AFAIK - there is no portable way to trap the overflow. I think the best we can hope for is automatic promotion of literals by the compiler/assembler. -J --
