floor() and ceil() functions

[Gambet]

After testing the floor() function I came to realize that it does not work. To double check, I asked napo to test it out, and he also concluded that it does not work. While noticing that the floor() function does not work, I realized that there is also not a ceil() function (or at least I can't find one anywhere), so I made both in hopes that it's updated into the engine.


Simple enough, really:

PHP Code:

public function ceil(num) {
 if (int(num) != num)
  return int(num) + 1;
 else return num;
}

public function floor(num) {
 return int(num);
}
