The number which corresponds to xx:yy, either for reading or setting a parameter, is
determined by the following formula:
– for storing to the Milltronics device:
value = (xx + 128) x 256 + (yy + 128)
– for reading from the Milltronics device:
xx = (value / 256) - 128
yy = (value % 256) - 128
where % is the modulus operator. This can be computed by finding
the remainder of an integer divide-by-256.
It may simplify programming to notice:
xx = (most significant byte of value) - 128
yy = (least significant byte of value) - 128
