Heh. :-). just for the record: 1. 1_000_000_000 was just for the sake of the example. It could also be: 2_435_279_145 or something else that is arbitrary. 2. The problem with 1E9 is that I think it's a floating point number (though Perl 5 may have some intelligence there). Not sure it matterns a lot for Perl but if you do something like 1.27E9 you may get weird side-effects due to: http://download.oracle.com/docs/cd/E19957-01/806-3568/ncg_goldberg.html (Oracle++ for fixing the old link from docs.sun.com after it was broken.)
