Unlimited numeric class based on deque

Abstract

This paper develops 2n based number system, studies the expression of digital symbols presented with built-in data type variable in programming languages and the calculation algorithm of 2n based numbers. It gives the implementation scheme of unlimited numeric class based on automatic scalable queue. In this scheme, one unlimited number is made up of two queues: one for integer part and one for decimal part, each element of the queue is one digital symbol of 2n based number system. The unlimited numeric class can express integer and decimal with unlimited digitals, it can be a member of base library of programming languages. © 2011 Springer-Verlag Berlin Heidelberg.
