This module is used by {{tl|val}}. == Use in other modules == ===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. <syntaxhighlight lang="lua"> local gaps = require('Module:Gapnum').gaps function example() local n = 123456.78900011 -- Example for just simple formatting of a number -- n_gaps will use the default, .25em gaps and no change in precision -- The result will have its gaps created with inline css -- But the result would look like: -- 123 456.789 000 11 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: local n_big_5 = gaps(n, {gap='1em', prec=5}) local n_small_10 = gaps(n, {gap='1px', prec=10}) end </syntaxhighlight> ===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) end </syntaxhighlight>
