Signed Integer Representation
We have been ignoring large sets of numbers so far; ie. the sets of signed integers, fractional numbers, and floating point numbers.
We will not talk about fractional number representation (10.3456) or floating point representation (i.e. 9.23 x 1013).
We WILL talk about signed integer representation.
The PROBLEM with signed integers ( - 45, + 27, -99) is the SIGN! How do we encode the sign?
The sign is an extra piece of information that has to be encoded in addition to the magnitude. Hmmmmm, what can we do??
