===gaps===
The <code>gaps</code> function can be useful for [[MOS:DIGITS|formatting]] in other modules that work with displaying large numbers.
<syntaxhighlight lang="lua">
local gaps = require('Module:Gapnum').gaps
</syntaxhighlight>
Using the <code>gaps</code> function, the first argument is the number to format. The second argument can be a table with keys that tell the module how to format. The table keys that can be used are:
* <code>gap</code> - a number with CSS units (px, em, en, etc) that define the size of the gap between numbers. If blank, the module will use <code>0.25em</code>.
* <code>prec</code> - a number that determines the precision of the decimal part of the number. If the precision is less than the number of digits, extra digits will be removed without rounding; if it is more, zeroes will be added to the end to create the desired precision. If blank, the module will use <code>-1</code>, which means the precision will be the same as the number given; no digits added or removed.
Note that the return statement is a table. This means more styling or text can be added to the wrapper span tag, but it may also mean that <code>tostring()</code> may be required when used in other modules.

local n_gaps = gaps(n)
-- Different gap size
-- These will format n into the same groups as above
-- But the spaces between the groups will be larger and smaller, respectively
local n_big_gaps = gaps(n, {gap='1em'})
local n_small_gaps = gaps(n, {gap='1px'})
-- Different precision
-- n_prec_5 will use the number 123456.78900
-- The result would look like:
-- 123 456.789 00
local n_prec_5 = gaps(n, {prec=5})
-- n_prec_10 will use the number 123456.7890001100
-- The result would look like:
-- 123 456.789 000 1100
local n_prec_10 = gaps(n, {prec=10})
-- Both different gaps and precision can be used:

===groups===
The <code>groups</code> function can be used in other modules to separate a number into groups as <code>gaps</code> does, but instead of a formatted <code>string</code>, the function will return tables whose elements are the separated groups.
<syntaxhighlight lang="lua">
local groups = require('Module:Gapnum').groups
function example()
-- This will return one table:
-- {123,456}
local n1 = groups(123456)
-- This will return two tables, each assigned to a different variable:
-- n2a will be:
-- {1,234}
-- n2b will be:
-- {567,89}
local n2a,n2b = groups(1234.56789)
-- This will return two tables:
-- An integer part is always returned, even if it is 0
-- n3a will be:
-- {0}
-- n3b will be:
-- {123,4567}
local n3a,n3b = groups(0.1234567)
-- Just like the other functions, a precision can be defined
-- precision is simply the second parameter
-- n4a will be:
-- {123}
-- n4b will be:
-- {456,700,00}
local n4a,n4b = groups(123.4567,8)
