in reply to "force string context"?

If you need to handle integers bigger than 2**31 (> 2147483646) you should use Math::BigInt. Is just not recomended to work with numbers outside of the range, will just not work!

    If your integers are less than about 2**51, there will be no loss of significant digits (because Perl will automatically start using doubles). If your integers will be less than 2**63, I'd prefer a 64int perl over Math::BigInt. (In fact, I always compile my perls to turn on 64 bit integer support).

      But to use 64int I need a 64bit CPU?

      And what is the option to enable that? I never compiled in this way and I'm interested to make some tests.

        No, all you need is a compiler being able to deal with it.

        For compiling options, please read the INSTALL, README and README.<your OS> files that come with the source.
