A Boolean encoding of arithmetic operations

Zbrzezny A.

Scientific Issues of Jan Długosz University in Częstochowa. Mathematics

2010

Vol. 15

In this paper we present algorithms for a Boolean encoding of four basic arithmetic operations on integer numbers: addition, subtraction, multiplication and division. Integer numbers are encoded in two's complement system as vectors of Boolean formulae, and arithmetic operations are faithfully encoded as operations on vectors of Boolean formulae.
