👉 Rotary computing is a method of performing arithmetic operations, primarily addition and subtraction, by physically rotating components rather than using electronic circuits. In this system, numbers are represented as binary sequences that are fed into a series of rotating wheels or disks, known as rotors. Each rotor represents a bit in the binary number, and as the rotors spin, they perform the necessary calculations based on the binary input. The results are then read out by comparing the positions of the rotors, a process known as "readout." This mechanical approach was historically significant before the advent of electronic computers, offering a tangible and efficient way to handle calculations. Despite being largely replaced by electronic methods, rotary computing remains a fascinating example of mechanical engineering and its application in data processing.
