Monks, I throw my unworthy knowledge at your feet for enlightenment. I wish only to understand. I have heard that the largest integer I can work with in Perl is 2,147,483,647 because this is the upper limit of 32 bits. And I have some code that uses the Set::IntSpan module and it does indeed start putting out invalid negative numbers over that amount. However, If I just do 
#!/usr/local/bin/perl -w
use strict;
my $x = 3147483648;
my $y = 3147483648;
my $a = $x + $y;
print $a;

I get the right answer. Why is this?

Eternally grateful for any wisdom offered.
