An alternative technique was developed that enabled computer hardware to work with signed numbers using slightly modified addition hardware. This technique is called two's complement arithmetic. Two's Complement. Two's complement is a way of representing negative numbers so that only Unsigned binary multiplication. Multiply by one bit at a time (partial products). Add partial products for answer. Same principle as in decimal (or any base b). Multiply n-bit numbers for a 2n-bit result. Page 10. 03b-10. Unsigned binary multiplication. Example. 1010 x 0011. Page 11. 03b-11. Signed numbers in real life. 8 Nov 2005 Signed numbers Basics. • So far, numbers are assumed to be unsigned (i.e. positive). • How to represent signed numbers? • Solution 1: Sign-magnitude - Use one bit to represent the sign, the remain bits to represent magnitude. – Problem: need to handle sign and magnitude separately. • Solution 2: One's Binary Representation Systems. • Integer Systems. – Unsigned. • Unsigned (Normal) binary. – Signed. • Signed Magnitude. • 2's complement. • Excess-N*. • 1's complement*. • Floating Point. – For very large and small. (fractional) numbers. • Codes. – Text. • ASCII / Unicode. – Decimal Codes. • BCD (Binary Coded Decimal). to represent the sign with a bit placed in the leftmost position of the number. The convention is to make the sign bit 0 for positive and 1 for negative. It is important to realize that both signed and unsigned binary numbers consist of a string of bits when represented in a computer. The user determines whether the number is Addition and Subtraction. ? Two instructions used for additions and subtractions: add and sub. ? Both instructions can be used on a pair of signed numbers or on a pair of unsigned numbers. ? One of the big advantages of 2's complement storage. ? No mixing of signed and unsigned numbers. ? IMPORTANT: The CPU 3. Number Systems. Four number system. ? Decimal (10). ? Binary (2). ? Octal (8). ? Hexadecimal (16). ? . 13. Negative numbers. Three representations. • Signed magnitude. • 1's complement. • 2's complement 18. Binary Arithmetic. • Addition / subtraction. • Unsigned. • Signed. – Using negative numbers Thus needs to be a consistent method of representing negative numbers in binary computer arithmetic operations. • There are various approaches, but they all involve using one of the digits of the binary number to represent the sign of the number. • Two methods are the sign/magnitude representation and the one's. All numbers in the computer are repre$
