<onlyinclude>'''<code>Expr</code>''' – Module with functions for any kind of expression in addition to the functionality offered by <code>#expr</code> parser functions.

== {{Anker|template}} Functions for templates ==
The standard functions are supposed to be used in <code>#invoke</code> and retrieve those parameters. Whitespace ahead and after any content is ignored.

; max {{Anker|max}}
: Retrieve maximum of a set of figures.
: All unnamed parameters are used for extremum calculation.
:* Parameter values may be empty or can contain expressions, which can be evaluated by <code>#expr</code> parser function.
:* Both [[American Standard Code for Information Interchange|ASCII]] [[Viertelgeviertstrich#Bindestrich-Minus|minus]] U+002D and U+2212 [[Minuszeichen|<code>&minus;</code>]] are [[#Unicode-Minus|accepted]].
:* Options are available as named parameters:
:** <code>minus</code> – minus sign coding in result; see [[#Unicode-Minus|below]]
:** <code>zeroBlank=1</code> – present zero as empty value
: The return value is an empty string (nothing), if no parameter at all or only empty values were provided. An error message for invalid <code>#expr</code> might occur as well. Otherwise that is the determined number in the specified formatting.
; min {{Anker|min}}
: Retrieve minimum in the same way as [[#max|max]].

=== {{Anker|templatePars}} Direct transclusion in templates ===
; TemplateMax
: Like [[#max|max]], but specific to [[Template:Max]] – use all parameters of the template around.
; TemplateMin
: Like [[#min|min]], but specific to [[Template:Min]] – use all parameters of the template around.

=== Unicode minus ===
The minus sign is treated as follows:
* On input values they may be used at will.
* If any input value contains a Unicode minus U+2212, this encoding will be used in the result.
* Optional <code>minus=1</code><br />Use Unicode minus only for resulting string.
* Optional <code>minus=-</code><br />Use ASCII hyphen only for resulting string.
A result with Unicode minus is by nature always a string.

=== Examples (test page) ===
A [[Wikipedia:Lua/Modul/Expr/test|test page]] illustrates practical use.</onlyinclude>

== {{Anker|Lua}} Functions for Lua modules (API) ==

All functions documented above may be used via <code>require()</code> in other Modules:
<syntaxhighlight lang="lua">
local lucky, Expr = pcall( require, "Module:Expr" )
if lucky then
Expr = Expr.Expr
else
-- Error; Expr contains error message
return "<span class='error'>" .. Expr .. "</span>"
end
</syntaxhighlight>
Then there is available:
; Expr( f, a )
: <code>f</code> – ''string'' with function name, as above
: <code>a</code> – ''table'' with parameter assignments
:* Values are not supposed to be of ''string'' type, but may contain a ''number'' itself.
:* Return values may be of type ''number'' or could be strings or <code>false</code>.

== Usage ==
General library; no limitations.

== Dependencies ==
None.
