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 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:
