Sinopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The two''s complement of a binary number is defined as the value obtained by subtracting the number from a large power of two (specifically, from 2N for an N-bit two''s complement). The two''s complement of the number then behaves like the negative of the original number in most arithmetic, and it can coexist with positive numbers in a natural way.A two''s-complement system or two''s-complement arithmetic is a system in which negative numbers are represented by the two''s complement of the absolute value; this system is the most common method of representing signed integers on computers. In such a system, a number is negated (converted from positive to negative or vice versa) by computing its two''s complement. An N-bit two''s-complement numeral system can represent every integer in the range −2N−1 to +2N−1−1.
