note 84861 rejected from function.abs by danbrown

Note Submitter: lkj d0t korn ---- Additional notes to my previous post. "(as PHP turns it automatically into a string or float)" I mean to say "(as PHP turns strings automatically into an integer or float)". Another thing I'd like to note is that the variable name $integer used in my examples aren't really advised as the function goes beyond simple integers. Initially, I used this function only for the handling of integers, hence the variable name. It is only later that I've discovered it goes beyond integers. 0 will also return to 0 (if that shouldn't be obvious). Perhaps it is better to make it return NULL instead of FALSE when it fails the is_numeric condition, so that there's no mix with the function's result to be false instead of actually 0, however only checking with '===' instead of '==' should solve this, I believe.
