Dear all, Im sure this is a simple question, but as we all know sometimes that its the simple questions that are the difficult ones. Im trying to work out the average of 10 numbers, so I am adding them to each other but the problem arises when I need to divide the answer by 10. I seem to vaguely recall that you have to apply the 2s complement method, but I am not sure. Can anyone please offer me some help to this trivial problem. many thanks Jason -- http://www.piclist.com hint: The PICList is archived three different ways.
