Whatever you do will be insignificant,but
the important is you do it!
It doesn't matter who you are, it's what
you do that takes you far!

Or, shorter (no need to use while _and_ //g):
use warnings;
use
Or you can try:
__BEGIN__
#!/usr/bin/perl
use warnings;
use strict;
my @decimals;
$_ = 'atom 12 N VAL A 1 12.435 13.66 34.6 32.1 32 a N';
push @decimals,$1 while (/(\d+\.?\d*)/g);
print "@decimals\n";
__END__

After second thought
This line:
my @y = grep { $_ if ($_ =~ /\d+/)} @list;
could be simplified with this:
my @y = grep { /\d+/ } split(/\s+/,$file);
Since grep { $_ if /\d+/ } wouldn't match on 0, but grep /\d+/ would.
I'm still wondering how can I do that with "unpack" :-(

Hi everybody,
Can we use substr function for a string like:
$file = atom 12 N VAL A 1 12.435 13.66 34.6 32.1 32 a N
can the decimal numbers be extracted using
$x= substr($file, offset, length)
(the exact field lenghts of each field are known).
Thanks in advance..
