I've got a plain text file with some random numbers seperated by comma's, like this:


How can I open the plain text file and count up the numbers and then divide them by the number of numbers ?
(sorry for my bad english)

in the example above I would like to get as result:
6,3 (1 digit behind the comma)
this is 5+6+4+7+5+5+6+9+10 / 9

use strict;

open(F, '< file.txt') or die $!;
my @digits = <F> =~ /(\d+)/g;
close F;
my $sum = 0;
$sum += $_ for @digits;
print "Result: ", $sum/@digits;
