Template:Overunderset/doc

This template combines the effects of 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|base|over|under}} or {{overunderset|base|over|under}}

which outputs as overbaseunder.

where:

base

the main symbol,

over

the symbol above the main symbol,

under

the symbol underneath the main symbol.

Application

Combined overset and underset

The effect of {{overunderset|b|a|c}} can be achieved by nesting {{underset|c|{{overset|a|b}}}} (or, equivalently, nesting underset into overset):

fooofoo + abc + foofoofooo + abc = fooofooo

but combining underset and overset may cause problems with vertical offset, particularly when there is only one combined application of templates on a line:

foodoodeee + foodoodaa,

foodoodaaa + foodoodee.

Using {{overunderset|base|over|under}} is one way around the problem by containing the over- and under- positions for symbols:

fooofoo + abc + foofooofooo + abc = fooofooo

foodoodeee + foodoodaa,

foodoodaaa + foodoodee.

Reduction to overset

With the under parameter empty:

1234567890 + ba + 1234567890 + ba + 1234567890

1234567890 + ba,

1234567890 + ba.

Reduction to underset

With the over parameter empty:

1234567890 + ab + 1234567890 + ab + 1234567890

1234567890 + ab,

1234567890 + ab.
