How do your statements: No, I didn't give oct a valid hex number, I gave it an invalid octal number which could have been understood as an otherwise valid decimal number. and No, the result of oct("108") is "8" but I think it should be undef. relate to each other? 108 is an otherwise valid decimal number. You also seem to be defending, or at least sharing, the OP's ideas. And the OP wants to have a function that given decimal input, returns the decimal representation - so oct 108 (or whatever name this function has) should return 108.

If you think that oct 108 should be undefined, and not 8, do you also think that $x = "10 dogs" + "5 chickens" should result in $x being undefined, and not 15? What about

print "Please enter a number: "; my $num = <>; printf "Its square is %d.\n" => $num * $num if $num =~ /^\d+$/;
Should that print "Its square is 0.", after issueing a warning?

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.
