Redundant Multiple-Valued Number Systems
Jon T. Butler, Tsutomu Sasao · 1997
Abstract : We survey number systems in which the digits are multiple-valued and the representations are redundant. In a redundant number system, there is at least one value that can be written in at least two ways. As a basis of comparison, we consider also non-redundant binary number systems, including the standard binary number system. We compare systems on the basis of redundancy - that is, how many redundant numbers exist.
