Template:SubSup/doc

This template provides a simple means of coding inline mathematical material that has subscripts and superscripts, for display in the same typeface as the surrounding text. The rendering is always done in HTML; this offers an alternative to using the TeX preprocessor via the  tags, which display the material in a serif typeface regardless of the typeface of the running text. Unlike with TeX/HTML rendering, the type size of the subscripts and superscripts is always reduced, in keeping with common practice in mathematics.

Usage
The first argument is assumed to be a quantity symbol, and is set in the oblique (“italic”) font of the typeface for the surrounding text. To have the base symbol in upright font, give the symbol before the template and give a blank first argument.

The subscripts and superscripts are set in upright font, in keeping with normal practice for numerals and descriptive subscripts. To set the superscript or subscript in oblique font, as for a subscript that itself is a variable, use the HTML  or  tags, or the wikimarkup for italics.

Note that to get only a superscript, a blank second argument must be given.

By default, a space of approximately 1/6 em is added after the symbol to prevent the oblique symbol from overlapping the upright superscript or subscript. To suppress this spacing, give the optional  parameter (any value other than zero is ignored); the s parameter is ignored if the first argument (for the base symbol) is blank. The s parameter may be given at any point in the argument list; the other arguments must be given in the order shown.

Examples
Subscript only:
 * gives $[ ] [$

Subscript only without spacing:
 * gives $[ ] [$

Superscript only:
 * gives $[ ] [$

Subscript and superscript:
 * gives $x a$

Subscript and superscript with base symbol in upright font:
 * gives X$x a$

Superscript with variables:
 * gives $x a$

To obtain a more mathematical font, the math template may be wrapped around any of these. E.g.
 * gives $x a$
 * gives $x a$
 * gives $x a$
 * gives $x a$

Compatibility
The template has been tested under Windows XP SP3 using Firefox 3, Internet Explorer 7, Opera 9.5, and Safari 3.1. Combined subscripts and superscripts do not display properly when zooming the text with Internet Explorer 7.
