Hello, Enric,

In this code int() just checks each row of the input file for an integer value.

It does not!

    fxn a yeager:~/tmp $ perl -le 'print int "0"'
    0

    fxn a yeager:~/tmp $ perl -le 'print int "21.34"'
    21

int() serves a different purpose (the one explained in its docs).

You need no int() call. Firts, the input file is assumed to be formed by numbers. And if you needed to check whether the numbers were well-formed you wouldn't use int().

Perl ony has scalar values, if you are thinking numbers vs strings you are doing it wrong.
