In Lua, "table" is a fundamental type that can be used either as an array (numerical index, fast) or as an associative array. The keys and values can be of any type, except nil. The following focuses on non-numerical indexes. A table literal is written as { value, key = value, [index] = value, ["non id string"] = value }. For example:
For example, to perform an element by element sum of two arrays, a and b to produce a third c, it is only necessary to write c = a + b In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x)
List comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation ( set comprehension ) as distinct from the use of map and filter functions.
Torch is an open source deep learning library for Lua. Varnish can execute Lua scripts in the request process by extending VCL through the Lua VMOD (Varnish module). [32] Vim has Lua scripting support starting with version 7.3. [33] VLC media player uses Lua to provide scripting support. Warframe uses Lua for HUD purposes and several other UI ...
A table is a sequence, optionally supplemented by named keys: digit["two"]="2". Several table functions like table.concat will only work with the numbered values and ignore named keys. The metatable offers a large, optional set of methods for altering table behavior. For example, you can define a table to be callable like a function.
Many software libraries are written in system programming languages such as C or C++. To use such libraries from another language, usually of higher-level , such as Java , Common Lisp , Scheme , Python , or Lua , a binding to the library must be created in that language, possibly requiring recompiling the language's code, depending on the ...
Allegro is a software library for video game development. [3] [4] [5] The functionality of the library includes support for basic 2D graphics, image manipulation, text output, audio output, MIDI music, input and timers, as well as additional routines for fixed-point and floating-point matrix arithmetic, Unicode strings, file system access, file manipulation, data files, and 3D graphics.
The BCMath library just uses strings as datatype. The GMP library uses an internal "resource" type. ^f The value of n is provided by the SELECTED_INT_KIND [4] intrinsic function. ^g ALGOL 68G's runtime option --precision "number" can set precision for long long ints to the required "number" significant digits.
