in reply to Extracting Unique Characters from a Array

This solution uses some moderately-advanced techniques, but I recommend you study the solution and perldoc what you don't understand. You will learn some really useful techniques!
#!/usr/bin/perl use strict; use warnings; use Carp; use Data::Dumper::Simple; my @array = qw( 7742.8858 7748.5855 5581.2272 1248.2257 6589.5586 5680.1886 8762.1898 5581.2272 5535.5795 6896.6571 6573.2575 6589.5586 5680.1886 5487.3275 5489.5633 6589.5586 5680.1886 ); my %unique = map { $_ => '' } @array; my @sorted_unique = sort { $a <=> $b } keys %unique; print Dumper(%unique,@sorted_unique);

It's all fine and dandy until someone has to look at the code.
