The use of several modules can increase the flexability of your code without introducing the potential errors mentioned by other responders.

use strict; use warnings; use v5.10.1; use Readonly; use List::Util qw(sum); use Regexp::Common; Readonly::Scalar my $NUMBER => qr/$RE{num}{real}/; while (my $line = <DATA>){ chop($line); say sum( $line=~/($NUMBER)/g ); } __DATA__ 86f,934e,92,102i,14,19,222,
