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

I had this thought before :)

now perl gives warning

Argument "0x41" isn't numeric in printf

Very clean, things we know are numbers and can unambiguously identify as numbers, we treat as numbers, all other stuff we warn about

But if definition of numeric was expanded to include more ambiguous num formats, then perl would need a new warning

treating "0x41" as numeric , might be wrong thing to do, silence with +"no warnings q/extranumeric/;"

I'm confused why perl-diddler hasn't posted use extranumeric; yet :D

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.
