calculatoire

Calculatoire is a French adjective used to designate things related to calculation or computation. In mathematics, computer science, and logic, it appears in phrases such as méthodes calculatoires or systèmes calculatoires to emphasize processes that proceed by calculation, algorithmic rules, or formal deduction.

The term is commonly attached to formal calculi and models of computation. In this sense, calculatoire speaks to the procedural aspect of computing: the steps, rules, and procedures that transform inputs into outputs. It is often contrasted with empirical or numerical approaches, though in practice the distinction is fluid, since many calculatoires are implemented as algorithms or simulations.

In francophone literature, the broader field concerned with computation is usually called informatique théorique (theoretical computer science). The related noun calculabilité (computability) and areas like complexité (complexity) are more standard, while calculatoire serves as an qualificative layer describing computational methods or perspectives.

In English-speaking contexts, the closest equivalents are computational or computability, and concepts are typically discussed under computability theory or theory of computation. See also computability, computational complexity, lambda calculus, automata theory.
