Module:Formatnum/doc: Difference between revisions

This module provides a number formatting functions. These functions can be used from #invoke or from other Lua modules.

This module is used by Module:Complex date and {{FXConvert}}

Use from other Lua modules

To use the module from normal wiki pages, no special preparation is needed. If you are using the module from another Lua module, first you need to load it, like this:

local mf = require('Module:Formatnum')

(The mf variable stands for Module Formatnum; you can choose something more descriptive if you prefer.)

Most functions in the module have a version for Lua and a version for #invoke. It is possible to use the #invoke functions from other Lua modules, but using the Lua functions has the advantage that you do not need to access a Lua frame object. Lua functions are preceded by _, whereas #invoke functions are not.

main

{{#invoke:Formatnum|main|x|lang=|prec=|sep=}}

mf.formatNum(x, lang, prec, sep)

wordify

{{#invoke:Formatnum|wordify|x|numsys=|prec=|lk=}}

mf._wordify(x, numsys, prec, lk)

Wordify x.

• numsys can be 'usa' (the default) or 'ind'
• prec is the digits of precision to output
• if lk is true ("on" for #invoke), the units will be linked
