This module provides a number of basic mathematical operations.]] local yesno, getArgs-- lazily initialized local p = {}-- Holds functions to be returned from #invoke, and functions to make available to other Lua modules. local wrap = {}-- Holds wrapper functions that process arguments from #invoke. These act as intemediary between functions ...
This Lua module is used on 1,620,000+ pages, or roughly 3% of all pages. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox .
Modulo operations might be implemented such that a division with a remainder is calculated each time. For special cases, on some hardware, faster alternatives exist. For example, the modulo of powers of 2 can alternatively be expressed as a bitwise AND operation (assuming x is a positive integer, or using a non-truncating definition):
The Lua API's design eliminates the need for manual reference counting (management) in C code, unlike Python's API. The API, like the language, is minimalist. Advanced functions are provided by the auxiliary library, which consists largely of preprocessor macros which assist with complex table operations. The Lua C API is stack based. Lua ...
In mathematics, an operator is generally a mapping or function that acts on elements of a space to produce elements of another space (possibly and sometimes required to be the same space). There is no general definition of an operator , but the term is often used in place of function when the domain is a set of functions or other structured ...
The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [ 1 ] and the LaTeX symbol.
A name in Lua is either an access of a local variable or a table lookup. [3] math.floor is a table lookup (of the string "floor") in the (global) math table, for example. Table lookups are slower, at runtime, than local variable lookups. Table lookups in tables such as the args table with its "specialness" are a lot slower.
The next line-width is not disturbed by large operators. The code for the math example reads: <math display= "inline" > \sum_{i=0}^\infty 2^{-i} </math> The quotation marks around inline are optional and display=inline is also valid. [2] Technically, the command \textstyle will be added to the user input before the TeX command is passed to the ...
