Line 27: Pure comes with an interpreter and debugger, provides automatic memory management, has powerful functional and symbolic programming abilities, and interfaces to [[Library (computing)\|libraries]] in [[C (programming language)\|C]] (e.g., for numerics, low-level protocols, and other such tasks). At the same time, Pure is a ''small'' language designed from scratch; its interpreter is not large, and the library modules are written in Pure. The syntax of Pure resembles that of [[Miranda (programming language)\|Miranda]] and [[Haskell (programming language)\|Haskell]], but it is a [[free-format language]] and thus uses explicit delimiters (rather than [[off-side rule]] indents) to denote program structure. The Pure language is a successor of the equational programming language Q, ~~created~~previously ~~formerly~~created by the same author, Albert Gräf at the [[University of Mainz]], Germany. Relative to Q, it offers some important new features (such as local functions with [[lexical scoping]], efficient vector and matrix support, and the built-in C interface) and programs run much faster as they are [[Just-in-time compilation\|compiled just-in-time]] to native code on the fly. Pure is mostly aimed at mathematical applications and [[scientific computing]] currently, but its interactive interpreter environment, the C interface and the growing set of addon modules make it suitable for a variety of other applications, such as [[artificial intelligence]], symbolic computation, and real-time multimedia processing. Pure [[Plug-in (computing)\|plug-ins]] are available for the [[Gnumeric]] spreadsheet and Miller Puckette's [[Pure Data]] graphical multimedia software, which make it possible to extend these programs with functions written in the Pure language. Interfaces are also provided as library modules to [[GNU Octave]], [[OpenCV]], [[OpenGL]], the [[GNU Scientific Library]], [[FAUST (programming language)\|FAUST]], [[SuperCollider]], and liblo (for [[Open Sound Control]] (OSC)). ==Examples== The [[Fibonacci numbers]] (naive version):
