OCaml (/ oʊ ˈ k æ m əl / oh-KAM-əl, formerly Objective Caml) is a general-purpose, high-level, multi-paradigm programming language which extends the Caml dialect of ML with object-oriented features. OCaml was created in 1996 by Xavier Leroy, Jérôme Vouillon, [5] Damien Doligez, Didier Rémy, [6] Ascánder Suárez, and others.
This article compares the syntax for defining and instantiating an algebraic data type (ADT), sometimes also referred to as a tagged union, in various programming languages. Examples of algebraic data types
In this case, a helpful alternative may be folded, computed or encoded tags, where the tag value is dynamically computed from the contents of the union field. Common examples are the use of reserved values, where, for example, a function returning a positive number may return -1 to indicate failure, and sentinel values, most often used in ...
Python uses the following syntax to express list comprehensions over finite lists: S = [ 2 * x for x in range ( 100 ) if x ** 2 > 3 ] A generator expression may be used in Python versions >= 2.4 which gives lazy evaluation over its input, and can be used with generators to iterate over 'infinite' input such as the count generator function which ...
OCaml: The Num library supports arbitrary-precision integers and rationals. OpenLisp: supports arbitrary precision integer numbers. Perl: The bignum and bigrat pragmas provide BigNum and BigRational support for Perl. PHP: The BC Math module provides arbitrary precision mathematics. PicoLisp: supports arbitrary precision integers.
C#, Java, Nim, [5] OCaml, Rust, [6] Python [7] Modula-3 is a programming language conceived as a successor to an upgraded version of Modula-2 known as Modula-2+ . It has been influential in research circles (influencing the designs of languages such as Java , C# , Python [ 8 ] and Nim ), but it has not been adopted widely in industry.
Reason, also known as ReasonML, is a general-purpose, high-level, multi-paradigm, functional and object-oriented programming language and syntax extension and toolchain for OCaml created by Jordan Walke, who also created the React framework, at Facebook.
A universe set is an absorbing element of binary union . The empty set ∅ {\displaystyle \varnothing } is an absorbing element of binary intersection ∩ {\displaystyle \cap } and binary Cartesian product × , {\displaystyle \times ,} and it is also a left absorbing element of set subtraction ∖ : {\displaystyle \,\setminus :}
