How about these:

#!perl -w
use strict;
my $fmt = "0b" . ("%06b" x 5);

sub b5ToInt { oct sprintf "0b%06b%06b%06b%06b%06b", @_ }

sub intToB5 {
 map { oct "0b$_" } unpack "(a6)5", sprintf "%030b", $_[0]
}

my $word = b5ToInt(1,2,3,4,5);
printf "word = %d = 0x%08x = 0b%030b\n", $word, $word, $word;

my @out = intToB5($word);
print "out = ", join(", ", @out), "\n";

Output:

word = 17314053 = 0x01083105 = 0b000001000010000011000100000101
out = 1, 2, 3, 4, 5

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.
