Edit: Ooops, my code only works for unsigned integers. I'll leave it here anyway, might at least come in handy for someone else at a later time...
Ok, Here's a simple example of how i did it as a test:
#!/usr/bin/perl
use strict;
use warnings;
my $val = 70000;
print "Saving Value: $val\n";
# ENCODE
my @bytes;
for(my $i = 0; $i < 3; $i++) {
$bytes[$i] = $val % 256;
if($val) {
$val = int($val / 256);
}
}
my $savebytes = pack("ccc", @bytes);
# DECODE
my @newbytes = unpack("ccc", $savebytes);
my $newval = 0;
while(scalar @newbytes) {
my $byte = pop @newbytes;
$newval = $newval * 256;
$newval += $byte;
}
print "Retrieved Value is: $newval\n";
Here's the output:
Saving Value: 70000
Retrieved Value is: 70000
I'm pretty sure there is a better way, but i'm not an expert on all this math stuff...
Edit: If you have a lot of numbers to encode/decode, you might want to consider putting that stuff into a C module or use Inline::C for speed.
Don't use '#ff0000':
use Acme::AutoColor; my $redcolor = RED();
All colors subject to change without notice.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
