There's more than one way to do things PerlMonks

 Need Help??
Maybe the following helps a bit clarifying what's what:

```#!/usr/bin/perl

use strict;
use warnings;

use Data::Hexdumper qw(hexdump);
use integer;

my \$Rm = '0xAAAAAAAA';
my \$Rb = hex \$Rm;
my \$Rc = pack 'l', \$Rb;
my \$Rd = unpack 'l', \$Rc;
my \$Re = \$Rd >> 31;
my \$Rx = pack 'l', \$Re;

print 'Rm: ', hexdump( \$Rm, { suppress_warnings => 1 } );
print 'Rb: ', hexdump( \$Rb, { suppress_warnings => 1 } );
print 'Rc: ', hexdump( \$Rc, { suppress_warnings => 1 } );
print 'Rd: ', hexdump( \$Rd, { suppress_warnings => 1 } );
print 'Re: ', hexdump( \$Re, { suppress_warnings => 1 } );
print 'Rx: ', hexdump( \$Rx, { suppress_warnings => 1 } );

printf "Rb = 0x%x\t Re = 0x%x\n",\$Rb, \$Re;
which displays
```Rm:   0x0000 : 30 78 41 41 41 41 41 41 41 41 00 00 00 00 00 00 : 0xAAA
+AAAAA......
Rb:   0x0000 : 32 38 36 33 33 31 31 35 33 30 00 00 00 00 00 00 : 28633
+11530......
Rc:   0x0000 : AA AA AA AA 00 00 00 00 00 00 00 00 00 00 00 00 : .....
+...........
Rd:   0x0000 : 2D 31 34 33 31 36 35 35 37 36 36 00 00 00 00 00 : -1431
+655766.....
Re:   0x0000 : 2D 31 00 00 00 00 00 00 00 00 00 00 00 00 00 00 : -1...
+...........
Rx:   0x0000 : FF FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00 : .....
+...........
Rb = 0xaaaaaaaa  Re = 0xffffffffffffffff

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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).
• Want more info? How to link or How to display code and escape characters are good places to start.
