All arithmetics in Perl is performed in binary. Though that's not really relevant, because the outcome would be the same if it were performed in any other base.
$ perl -wE 'say 4 + 5' # uses binary addition under the hood 9
It's just the input and output of numbers that decimal by default; but as others have shown you, there are ways to achieve binary input too.
So I guess the real question is: what do you want to achieve?
