    Type system - Wikipedia

    https://en.wikipedia.org/wiki/Type_system

    In programming languages, a type system is a logical system comprising a set of rules that assigns a property called a type to the various constructs of a computer program, such as variables, expressions, functions or modules. These types formalize and enforce the otherwise implicit

    Usage overview

    An example of a simple type system is that of the C language. The portions of a C program are the functiondefinitions. One function is invoked by another function. The interface of a function states the name of the function and

  2. Pure type system - Wikipedia

    https://en.wikipedia.org/wiki/Pure_type_system

    In the branches of mathematical logic known as proof theory and type theory, a pure type system (PTS), previously known as a generalized type system (GTS), is a form of typed lambda calculus that allows an arbitrary number of sorts and dependencies between any of these. The framework can be seen as a generalisation of Barendregt's lambda cube, in the sense that all corners of the cube can be represented as instances of a PTS with just two sorts. In fact, Barendregt (1991) fra…

      • Formally, type theory studies type systems. A programming language must have the opportunity to type check using the type system whether at compile time or runtime, manually annotated or automatically inferred. As Mark Manasseconcisely put it: Assigning a data type, termed typing, gives meaning to a sequence of bits such as a value in memory or some object such as a variabl…

      Common Type System är en standard som specificerar hur datatyper ter sig i ett datorminne. Målet är att låta program som är skrivna i olika programspråk lätt ska kunna utbyta information med varandra. I ett programspråk kan en typ beskrivas som en definition av en mängd med värden, och de tillåtna operationerna som kan utföras med dessa värden. Specifikationen för …

            A type system is that component of a typed language that keeps track of the types of vari-ables and, in general, of the types of all expressions in a program. Type systems are used to de-termine whether programs are well behaved (as discussed subsequently). Only program sources
