since someone else has already posted a reasonable solution, I'll add a couple of notes:

When discussing numbers, it is important to note the boundary. You said integer, but are negatives possible? is the range outside the 16bit signed limit? 32bit signed limit? is there any limit at all?

When looking for performance solutions, you should also provide information on the platform. Do you need portability? are you on a win32 or unix platform? are you capable of understanding C code? (an Inline::C function would make short work of your problem)

And if possible, providing context is valuable. There have been numerous times when people have posted a very limited description, asking a very targetted question, and it was found that the entire operation could be avoided by use of a different overall strategy. Context helps experienced monks identify those situations.

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.
