French to English translations [PRO] Tech/Engineering - Mathematics & Statistics / Calculation within a µcontroller program
French term or phrase:arithmétique entière
"Le reste du logiciel consiste à transformer le nombre d'impulsions en tours/minute. Tout est implémenté en arithmétique entière."
This is in the description of the µcontroller program used to construct a home-built rev counter for car engines.
I assume it means 'whole number arithmetic' (as distinct from 'floating point' arithmetic), but I haven't been able to find much on the NET that specifically corroborates that. Is there anyone out there who knows rather more about mathematics in FR?
Explanation: as you surmised -- contrasts with floating-point arithmetic. Entirely typical for a micro-controller to use only integer arithmetic.
"Toutes les opérations que l'on vient de voir ne concernent que l'arithmétique entière. Notre exemple. de paye, pour être plus réaliste, devrait utiliser des nombres avec partie fractionnaire."
"Let's look at another facet of floating-point arithmetic. If you've used integer arithmetic much, you know that division by zero triggers an ..."

Observation: integer arithmetic is «arithmétique entière» or «arithmétique d'entier»; floating-point arithmetic is «arithmétique flottante» or «arithmétique de virgule flottante».

Further observation: as mediamatrix points out, there exists also "fixed point" arithmetic"/«arithmétique de virgule fixe». However this is a high-level software construct and "under the hood" it is really only scaled integer arithmetic. In lower-level software terms, and in hardware terms, only two kinds of arithmetic operations exist, namely integer and floating-point.
