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.
