By that point in the code, there are no negatives anyway (see Re: Loosing Negative Values in Array Ref).

    But how could I print my results and get for this particular element as an example this result:
    [ 'Auser Ferro', '987778999', '2008-11-30', 'W', '888', '0', '0', '0', '1', '2', '4', '0', '-5.00', '0', '0', '0', '0', '0', '0', '2.0', '2008', '1112399' ],

    Notice the "-5.00". Thats what I am looking for.

    No.

    Here, I think this is what you want:

    for my $aref_acc_num (sort { $a->[0] cmp $b->[0] } values %$acc_num) { push @$all_dta_acc_num, my $tmp = []; for my $aref (@$aref_acc_num) { for my $i (0..1) { $tmp->[$i] = $aref->[$i]; } for my $i (2..$#$aref) { if (!defined($tmp->[$i])) { $tmp->[$i] = $aref->[$i]; } elsif ($tmp->[$i]=~m/^[+-]?\d+$/) { #numeric $tmp->[$i] = $aref->[$i] if $aref->[$i] > $tmp->[$i]; } else { $tmp->[$i] = $aref->[$i] if $aref->[$i] gt $tmp->[$i]; } } } }
      This is very close, see the values for "Zilda Mil", it should display "14.0" but instead its getting the "9.0".

        Hmmm, yes, this is because it's using 'gt' rather than '<'. I copied the regex from your program. The best solution (if you're on Perl 5.8 or later) is to use looks_like_number:
        use Scalar::Util 'looks_like_number'; for my $aref_acc_num (sort { $a->[0] cmp $b->[0] } values %$acc_num) { push @$all_dta_acc_num, my $tmp = []; for my $aref (@$aref_acc_num) { for my $i (0..1) { $tmp->[$i] = $aref->[$i]; } for my $i (2..$#$aref) { if (!defined($tmp->[$i])) { $tmp->[$i] = $aref->[$i]; } elsif (looks_like_number($tmp->[$i])) { $tmp->[$i] = $aref->[$i] if $aref->[$i] > $tmp->[$i]; } else { $tmp->[$i] = $aref->[$i] if $aref->[$i] gt $tmp->[$i]; } } } }
        If you're on an earlier Perl, see perlfaq4.
