Answer 1

@ValentinHacker is offtopic ;P

Your mistake is when you divide by two the 'num' variable: this give you floating result, but you're expecting integer value...

There is mainly 2 ways to fix it:

num = Math.floor(num / 2);

or :

num = (num- rem)/ 2;

Answer 2

(Put a "return false" at the end of your function...)
