On a New Method of Adding and Subtracting Binary Numbers on High Speed Digital Computers

摘要

A new algorithm of adding and subtracting binary numbers is given. It consists of the preliminary layout of orders of mantissas of the initial pair of numbers into special groups of orders and in the successive operation according to two different rules without any carries. This method of addition and subtraction has some advantages: some possible increase of the accumulator quick-response at the corresponding realization of the line making the layout, then the possibility of operation only in direct code. The algorithm itself is also useful for calculators and programmers who make binary operations on paper. (Author)
