0350. How are negative numbers
stored?
Negative numbers are stored as their
compliments. A compliment may be thought of as the mirror image of a number.
In binary, that means that whenever we see a 1, we change it to a 0, and
whenever we have a 0, we change it to a 1.
For example, the number 196 would be
stored as 00000000110001002 (on 16-bits). The number -196 would be
stored as:
0000000011000100
