If you need the exact amount, don't change the $old_amount while creating $new_amount. So you can use $old_amount later.

There is no way to back. Both Ceil() and floor() functions can't give you what you want.

You can't, once you round a value you get rid of the extra precision. This precision is lost. However, the old value is still stored in the $old_amount variable.
