- The INT16 class is used to represent 16 bit signed integers
- independently of the operating system or hardware platform used.
- It works by separating 16-bit values into two separate byte
- values and reordering the bytes lowest-order to highest-order.
- An INT16 type has a base 10 positive limit of 32,767 and a
- negative limit of 32,768.
