 Replying to [comment:1 voldemortensen]:
 > My real question though, is what is the need for the `default`
 parameter? I can't see a reason someone would want anything but false if
 the thing being checked isn't an integer.

 It might be preferable to return a WP_Error rather than false. I'll add
 that as a specific test case.

 Mainly, I've included it to match the PHP signature.

 Thanks for picking up the docblock changes needed. I'll fix them up.
