'''Template:Gaps''' outputs its unnamed arguments in order, applying the <code>margin-left: 0.25em</code> [[برگه‌های سبک آبشاری]] rule to all but the first, so that there will be gaps of 0.25em between the arguments. The whole output has the <code>white-space: nowrap</code> rule so that it will not be broken across several lines.

It supports up to twenty unnamed arguments. In addition, it supports the '''<code>base</code>''' and '''<code>e</code>''' arguments which can be used for numbers in [[نماد علمی]]. The base will be assumed to be 10 unless otherwise specified; a [[hyphen-minus]] "-" in the exponent will be automatically substituted by a [[minus sign]] "&minus;". It also supports the arguments '''<code>lhs</code>''' and '''<code>u</code>''' for putting left-hand sides and units within the non-breaking span (see examples below).

See [[Wikipedia:Manual of Style (dates and numbers)#Large numbers]] and [[Wikipedia:Manual of Style (dates and numbers)#Decimal points]] for information about where to put the gaps in numbers.

===Performance impact===
Template:Gaps allows up to 20 parameters, and displays the gaps by setting the left-margin space of each group. The gaps are not actual spaces, so a copy/paste of the text is treated as connected, consecutive text. Template:Gaps is coded with minimal wikitext [[markup]], so equivalent hand-coded markup could not be much shorter. Counting the length of the span-tags, there can be 15,800 instances of 2-part {gaps}, or 9,500 uses of 3-part gaps, or 6,800 with 4-part gaps (etc.), per page. The template uses a minimal [[m:HELP:Expansion depth|expansion depth]] of only 2 levels (of the if-else nesting limit, such as 40 maximum), and if those 2 levels are exceeded, only the first portion will be shown. Although the text, as displayed, is consecutive as on-screen text, {gaps} for a number cannot be used in a calculation because the internal markup contains the invisible &lt;span> tags which would be invalid text in typical numeric processing.
