Unformatted text preview: ckwise or counterclockwise. The electronic circuitry for storing and performing computations on two-valued signals is very simple and reliable, enabling manufacturers to integrate millions of such circuits on a single silicon chip. In isolation, a single bit is not very useful. When we group bits together and apply some interpretation that gives meaning to the different possible bit patterns, however, we can represent the elements of any finite set. For example, using a binary number system, we can use groups of bits to encode nonnegative numbers. By using a standard character code, we can encode the letters and symbols in a document. We cover both of these encodings in this chapter, as well as encodings to represent negative numbers and to approximate real numbers. We consider the three most important encodings of numbers. Unsigned encodings are based on traditional binary notation, representing numbers greater than or equal to 0. Two’s complement encodings are the most common way to represent signed integers, that is,...
