( #3333=superdoc: print w/replies, xml ) Need Help??

A GRT on packed negativity indicator and value seems to work.

use 5.026; use warnings; say for map { unpack q{xl>}, $_; } sort map { my $neg = $_ < 0 ? 1 : 0; pack q{Cl>}, $neg, $_; } -4 .. 4;

The output.

0 1 2 3 4 -4 -3 -2 -1

I hope this is useful.

Update: I just noticed that Tux posted exactly the same method while I was posting this.

Update 2: Ah! Not quite the same, negativity indicator not required apparently.

Cheers,

JohnGG

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 or How to display code and escape characters are good places to start.
