I have added the value-return for methods that operate upon the number. And I have added the printed output from useit.pl.

In addition I finally became a monk :-) ( yes I do have that fresh-car smell now and I am confused ) and I have also posted the tutorial as a full-fledged node. I would be grateful if a moderator deleted the node that was only a link to the document.

An aside:
I consider the background very Art-Deco and it lends character to my site. Herveus, the formatting problems you mentioned are pretty horrible - I have never experienced them in my browser, would you be kind enough to tell me your browser type+version? Thank you for notifying me. ( as well, all of the content on the page was in pre ).

update (broquaint): dropped <pre> tags and added formatting
