Abstract

Official abstract text for this publication.

An arithmetic device includes a database that stores a first indicator representing a base unit included in a unit system being assigned with a prime number other than a prime factor of a prefix, and a second indicator derived by combining the base units, in a form of a simple fraction; a conversion section that obtains a plurality of physical quantities each including a quantity, a prefix, and possibly a unit, to derive a third indicator by converting the unit into the first indicator and multiplying the converted first indicator by the prefix, or when the unit belongs to the derived unit, by converting the unit into the second indicator and multiplying the converted second indicator by the prefix; and an arithmetic section that performs calculation between the quantities of the plurality of physical quantities and between the third indicators.

First claim

Opening claim text (preview).

What is claimed is: 1. An arithmetic device comprising: a database implemented by a memory, that stores a first indicator representing a base unit included in a unit system being assigned with a prime number other than a prime factor of a prefix which is expressed with a base including the prime factor and an exponential part, and a second indicator representing a derived unit expressed, by combining the base units, in a form of a simple fraction including a numerator and a denomi…
