Starting at the last digit and moving backwards, you add up every other digit. Then, you double the left-out digits, and add the digits of these results to the original sum. If this satisfies sum mod 10 == 0 then the card is valid.</p> <p>This is also explained at <a href="http://www.beachnet.com/%7Ehstiles/cardtype.html" rel="nofollow">http://www.beachnet.com/~hstiles/cardtype.html</a></p>

This recipe cannot handle too large of numbers, but does act as a simple solution for most cases.</p>

Revision 10. </p> <p>This function converts 0 and <em>positive</em> integers (or their string representations) to their ordinal values. For example, it would convert 0 to "0th", 1 to "1st", 2 to "2nd", 3 to "3rd" and so on.</p>
