If you don't need to do any number-crunching on $a, why not use this:
$a = "3000000000000011";

Floating point numbers are imprecise. There are only so many digits of precision available, so you can't expect perl to be able to preserve the last "1" if you do something like this...
print 1000000000000000000000000000001
