The UINT16 class is used to represent 16 bit unsigned integers
independently of the operating system or hardware platform used.
It works by separating a 16-bit value into two separate byte
values and reordering the bytes lowest-order to highest-order.
An UINT16 type has a base 10 positive limit of 65,535.
