Sort/cellNum – Module with functions for generation of sortable number values in tables and for advanced number formatting.

f

Format number.

Parameters of template transclusion around:

none

Parameters of #invoke – all optional:

n

(Base) Number (mantissa)

Typographic minus sign permitted.

Dot . as decimal separator expected, but local project decimal separator is valid as well.

Machine readable format 1.234E56 for exponential representation (base 10) is also possible. This will trigger presentation with the same exponential number.

Grouping (thousands or other) separator not recommended, since disambiguous interpretation may occur. Dot . as decimal separator will precede.

Default: 0

exp

Exponent (to the power of ten).

Integer number expected.

Typographic minus sign permitted.

This will trigger presentation with exponential number (so-called “scientific notation”).

pre

Short prefix.

Appended to value without line break; normal whitespace.

plus

Positive Values (including zero) presented with preceding plus sign.

post

Short postfix.

Appended to value without line break; normal whitespace.

pad

Attempt to align decimal separators based on left or right edge.

Positive integer number: Count of digits following decimal separator to align (for left-to-right scripting: right-aligned).

Negative integer number: Count of digits preceding the value (for left-to-right scripting: left-aligned).

cell

If 1 then precede required table syntax for sortable number values.

Otherwise create <span> if necessary.

class

Universal attribute: space separated list of class names

style

Universal attribute: CSS declaration

URL and quotation marks " are not permitted.

id

Universal attribute: fragment ID

lang

Universal attribute: language code

Only if not matching page language

dir

Universal attribute: writing direction, either ltr or rtl

Only if not matching page language

cssNum

Page name of a TemplateStyles page, for general formatting

cssNumExp

Page name of a TemplateStyles page, for formatting with exponential numbers

Returns: Wikitext.

• On invalid input an error message will be returned.

failsafe

Version ID: 2025-01-27

optional parameter 1 – required version, or keyword wikidata or keyword ~

Returns:

• empty, if minimal version condition not matched
• local version otherwise, or registered version on Wikidata (2025-01-27) when keyword wikidata
• empty, if keyword ~ and a registered version on Wikidata is the same as local; otherwise local version ID ()

Presentation

• Always typographic minus sign.
• Always local project decimal separator.
• Grouping separator (thousands or other) symbol according to local project customization.
• Multiplication sign between mantissa and 10 according to local project customization and might be improved against · which is difficult to recognized.

Parameter format

• Both simple ASCII and typographic minus sign possible.
• Both dot or local project decimal separator possible.
• Syntax error in input(e.g. n-dash rather than typographic minus, or letter „O“ than digit zero) will be marked.

Sorting

• Preceding text or typographic minus sign do not influence sorting order.
• All cells with simple figures or other templates in family can be combined.

Padding

• It will be tried to arrange decimal separators one below the other integrated for the entire column.
• For each cell in column the same position is provided, and the individual whitespace to be probaly inserted for each cell and number will be computed.

Copy & Paste

On copy & paste of single numbers or entire tables the local project optical presentation will be replaced by machine-readable international data format. That does permit to insert easily values into other templates or external calculation programs:

• ASCII hyphen rather than typographic minus sign
• Dot as decimal separator
• No (thousands) grouping

Rather than the term ×10 the letter E will be copied, which yields to a common format for many programming languages.

All functions described above can be used by other modules:

local lucky, Sort = pcall( require, "Module:Sort/cellNum" )
if type( Sort ) == "table" then
    Sort = Sort.Sort()
else
    -- failure; Sort is the error message
    return "<span class=\"error\">" .. Sort .. "</span>"
end

Subsequently there are available:

Sort.f(arglist)

Reduce enhanced JSON data to strict JSON and analyse for errors.

• arglist – table with parameters; as for f
  Components, every string will get trimmed:
  • n – number|string; parsed as in template
  • exp – number|string; parsed as in template
  • pre – string
  • plus – boolean|string
    • string – parsed as in template; 1 → true
  • post – string
  • pad – number|string
  • cell – string|boolean|table
    • string – parsed as in template; 1 → true
    • table – mw.html object, which will be attributed and filled with content.
  • class – string
  • style – string|table, plain code or property name mapping
  • id – string
  • lang – string
  • dir – string
  • cssNum – string|title
  • cssNumExp – string|title
  • frame – object with frame, if at hand; otherwise nil

returns: string with wikitext or attribution of cell object

Sort.failsafe(atleast)

Version ID

• atleast
  optional
  nil or required version or "~" or "wikidata"

returns: string or false

• Sort/cell – Library with basic functions on table attributes

The module is working for all languages and number formattings, even for right -to-left scripting. Grouping (thousands or other) is derived automatically from local project; mostly 3, but some cultures use 4 or 5.

Adaption to local decimal separator and adaption of (thousands) grouping separator is to be done by TemplateStyles:

• Template:ZahlZelle/styles #I18N

A second one is configuring multiplication sign and 10ⁿ appearance:

• Template:ZahlExp/styles

Local page names can be provided via cssNum and cssNumExp assignments.
