Unsigned Overflow
In this class I will use 8 bit precision most of the time, 16 bit occassionally.
Overflow occurs when I add or subtract two numbers, and the correct result is a number that is outside of the range of allowable numbers for that precision. I can have both unsigned and signed overflow (more on signed numbers later) 8 bits -- unsigned integers 0 to 28 -1 or 0 to 255.
16 bits -- unsigned integers 0 to 216-1 or 0 to 65535
