Hi all. I'm new to this site and also to Perl. Was wondering if I could get some guidance.

I have a csv file in the following format: 
25.484000,23.327000,.000000,27.026000,26.616000,28.414000,21.704000
47.292000,27.944000,18.266000,18.702000,4.384000,26.765000,43.507000
21.773000,28.077000,.000000,25.974000,30.354000,17.996000,7.765000
25.484000,23.327000,.000000,27.026000,26.616000,28.414000,21.704000
47.292000,27.944000,18.266000,18.702000,4.384000,26.765000,43.507000
21.773000,28.077000,.000000,25.974000,30.354000,17.996000,7.765000

I need to parse out the data to only 3 decimal places.

I have the following code to work on the CSV file but cant get my print statements correct to truncate the numbers.

    #!/usr/bin/perl
    use strict;
    use warnings;
    use Text::CSV;

    my $file = '112008.csv';
    my $output='112008.txt';

    my $csv = Text::CSV->new();

    open (CSV, "<", $file) or die $!;
    open(OUTFILE,">$output") || die "Can't open file $output";


    while (<CSV>) {
        if ($csv->parse($_)) {
            my @columns = $csv->fields();
        printf OUTFILE "@columns\n";
        } else {
            my $err = $csv->error_input;
            print "Failed to parse line: $err";
        }
    }

    close CSV;

Any help would be appreciated.
