Template:Gaps outputs its unnamed arguments in order, applying the margin-left: 0.2em CSS rule to all but the first, so that there will be gaps of 0.2em between the arguments (the nominal width of a thin space. The whole output has the white-space: nowrap rule so that it will not be broken across several lines.

It supports up to twenty unnamed arguments. In addition, it supports the base and e arguments which can be used for numbers in exponential notation. 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 "−". It also supports the arguments lhs and u for putting left-hand sides and units within the non-breaking span (see examples below).

See Wikipedia:Manual of Style (dates and numbers) § Delimiting (grouping of digits) for information about where to put the gaps in numbers.

Performance impact[edit]

Template:Gaps allows any number of 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. 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 <span> tags which would be invalid text in typical numeric processing.
