* CONSTRAINTS

* This module does not handle data which is considered out of range by the

* application(i.e. fixed constants which represent error condition)

*

* Maximum weight value must be limited to 128 to prevent an overflow

* condition during the calculation.

*

* The internal data type must be large enough to handle the calculations.

* The maximum possible internal value

* = Max Input Value * (weight - 1) + Max Input Value

* If a maximum weight of 128 is used, the internal data type should be 2

* times the size of the input data type.
