    If the inputs are two integers, the result from any arithmatic will be fixed point, not floating point. Fixed point is just an integer with a 2^n offset

    You havent specific anything about the system - how many samples to average? where the values come from, what the number sizes are? you havent even posted any code that even attempts to do the averaging yet.
