I found this thread to be very interesting. It motivated me to read most of the references. My conclusion is that any application which needs integers even close to 2**53 probably should not be written in native Perl. Even if you can make it work, future changes are likely to introduce subtle bugs. Use either the pragma bigint or the module Math::BigInt. If execution time is a problem, consider using a language with typed variables such as 'C' or 'FORTRAN'.
