++ for suggesting a pseudo random generator! :)

This thread became (as usual) so long b/c the OP doesn't give us much detail, like

motivation: why the numbers need to be random
quantity: how many of them need to be generated
performance: how fast the solution needs to be

My first guess was to suggest a very simple algebraic Linear congruential generator where each element in the sequence is predictable and collisions are avoided.

But as usual because of lack of information we try to answer a wide range of possible questions. :(

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.
