Arithmetic Algorithms in a Negative Base
P.V. Sankar, Sveta Chakrabarti, E. V. Krishnamurthy · IEEE Transactions on Computers · 1973
Algorithms are described for the basic arithmetic operations and square rooting in a negative base. A new operation called polarization that reverses the sign of a number facilitates subtraction, using addition. Some special features of the negative-base arithmetic are also mentioned.
