Logarithmic Representations

Pp. 127-132 (6)

Abstract

Some types of calculation emphasise multiplication and division over addition and subtraction. Representing numbers as their logarithms accelerates multiplication and division, but slightly complicates addition and subtraction. This chapter gives a brief overview of logarithmic representations and their arithmetic.

Keywords:

Logarithmic representations, logarithmic arithmetic, implementation of logarithmic arithmetic.
