The INT32 class is used to represent 32 bit signed integers
independently of the operating system or hardware platform used.
It works by separating a 32-bit value into four separate byte
values and reordering the bytes lowest-order to highest-order.
An INT32 type has a base 10 positive limit of 2,147,483,647 and
a negative limit of 2,147,483,648.
