Abstract

This correspondence introduces a new number system, called the Focus number system which "focuses" on available resolution near zero much like an operational amplifier "focuses" on tiny deviations near virtual ground. This number system is supported by algorithms providing addition, multiplication, and higher order functions in a bare microcomputer at speeds rivaling those of existing integer arithmetic [1]-[3] performed with a costly arithmetic unit.
