ထႅမ်းပလဵတ်ႉ: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}}.

ပိူင်တႅမ်ႈ

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 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 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.
