in reply to perl rand() function

Yes, it is zero inclusive, however, I wouldn't be waiting around for perl -e '1 while rand' to finish within my lifetime.

    I'm so sorry that MeowChow was diagnosed as terminally ill with less than 1 second expected to live! I'm just glad the submit button got pressed before the end.

    Update: To be more informative rather than just humorous, I'll note that     perl -MConfig -e 'print $Config{randbits}'
    reports 15 for me. If I managed to build Perl such that this value got all the way up to 32, then I'd project MeowChow's life expectancy at a bit under 45 minutes. If I got that up to 48, then we'd be talking closer to 5 years. And if I got it up to 64, then I'd agree with MeowChow that waiting around 350,000 years wasn't worthwhile. (:
