మూస:Overunderset/doc

This template is combines the {{overset}} and {{underset}} templates into one.

The template names {{Overunderset}} and {{Underoverset}} are synonymous and can be used interchangeably: {{Underoverset}} redirects to {{overunderset}}.

Syntax

The code is:

{{underoverset|a|b|c}} or {{overunderset|a|b|c}}

where:

1. the first parameter is the main symbol,
2. the second parameter is the symbol above the main symbol,
3. the third parameter is the symbol underneath the main symbol.

Application

Combined overset and underset

The effect of an can be achieved by combining underset followed by overset:

1234567890 + aba + 1234567890 + aba + 1234567890

but sometimes one combination will not work, particularly when there is only one combined application of templates on a line:

1234567890 + aba,

1234567890 + aba.

The overunderset is one way around the problem using by containing the over- and under- positions for symbols:

1234567890 + bac + 1234567890 + bac + 1234567890

1234567890 + bac,

1234567890 + bac.

Reduction to overset

With the third parameter empty:

1234567890 + ba + 1234567890 + ba + 1234567890

1234567890 + ba,

1234567890 + ba.

Reduction to underset

With the second parameter empty:

1234567890 + ab + 1234567890 + ab + 1234567890

1234567890 + ab,

1234567890 + ab.
