A system that is used to represent negative numbers.
Binary Numbers: The complement system is used extensively in computing with binary numbers, where each digit can only take on the values 0 or 1.
Ones' Complement: A method of representing negative numbers by flipping all the bits of the positive number.
Two's Complement: A more popular method of representing negative numbers in computing. It involves taking the ones' complement of a number and adding one to it.
Sign-Magnitude Notation: Another approach to representing negative numbers by making the leftmost digit represent the sign (+ or -) of the number.
Floating-Point Numbers: A way of representing decimal numbers in binary with a significant and an exponent, where the complement system is used for negative exponents.
Overflow and Underflow: Consequences of arithmetic operations on binary numbers that exceed the range of representable numbers, leading to errors in computation.
Binary Coded Decimal (BCD): Another number system used in digital electronics, where each decimal digit is represented by its binary equivalent.
Octal and Hexadecimal Number Systems: Alternative number systems that are more compact than binary, used for compactly representing binary numbers.
Radix Complement: A generalization of the complement system for any base radix, where the complement is defined as the difference between the radix and the number.
Arithmetic with Complement Systems: The basic operations of addition, subtraction, multiplication, and division in binary using the complement system, with some special rules for handling negative numbers.
