And yes I am acutely aware that the basic algorithm for finding out max, min etc. from a list has actually go through the list. I was just looking for utilities, commands, or whatnot that can make it well ... look nice would probably be the best explanation. Something that does not need extra curly brackets and extra declared variables. Extra space and hmm more general eyestrain. The question was more motivated by general curiosity than an actual need for this current problem. Which I have already solved (probably quite horribly as people soon will point out I guess :D)

edit: in code I shift off the first element -because it is a header and therefore not numerical.

Well, ok, then, in addition to other's versions ++ mine:

#!/usr/bin/env perl

use strict;
use warnings;

my @akj = (0.11, 0.05, 0.02);

print join ",", @akj if grep {$_>0.1} @akj;

Well that's a quite nice and clean looking piece. Something like that I was looking for. Also looks like chessgui-s premonitions were right. :D
