Hi dbdiaz

Even though you already got the answer to your question: the ** operator described in perlop, I wanted to give you some advice: you should check the perl.org Online Library. There, you will find several books with the full text available. For instance, in the book Impatient Perl, you have that the numeric functions are described starting in page 15 (by the way, the ** operator is described on page 16).

I hope this helps

Cheers,
