For digital implementation, the signed digit quaternary numbers are represented using 3-bit 2's compliment notation. In this paper, a simple and new technique of binary (2's compliment) to QSD conversion is proposed and described..Keywords: quaternary sign digit(QSD), fast computation, ...

Addition and subtraction of signed numbers is done in the same manner as for unsigned numbers. However carry (or borrow) is simple ignored. Unlike unsigned number carry (or borrow) does not mean overflow or error. Doubling of a signed number can be done by shift left. However, halving of...
integer math. The ALU doesn't know about signed/unsigned; the ALU just does the binary math and sets the flags appropriately. It's up to you, the programmer, to know which flag to check after the math is done. If your program treats the bits in a word as unsigned numbers, you ...
Positive integers, including zero, can be represented as unsigned numbers. However, digital systems, such as the computer, must be able to handle both positive and negative numbers. To represent negative integers, we need a notation for negative values. In ordinary arithmetic, a negative number ...
1. get the binary representation of its absolute value;2. add 1 to that representation.Of course, there're restrictions of limited memory space.In this way, negative integers r stored in the memory in quite a same way as positive ones.e.g. 1111 1111 = -1;However, for a unsigned ...
