Usage #

If you know exactly which function you want to check, you can just type its name into the Function name field, fill its argument fields that will show up and then hit the "Execute!" button.

A basic documentation is displayed when a function is selected through the Function name field. Click the Show more link to unhide the rest of the documentation. Click the Show less link to hide it again.
