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}}.
The code is:
{{underoverset|base|over|under}}
or {{overunderset|base|over|under}}
which outputs as over base under .
where:
base
the main symbol,
over
the symbol above the main symbol,
under
the symbol underneath the main symbol.
Combined overset and underset [ edit ]
The effect of an can be achieved by combining underset followed by overset:
1234567890 + a b a + 1234567890 + a b a + 1234567890
but sometimes one combination will not work, particularly when there is only one combined application of templates on a line:
1234567890 + a b a ,
1234567890 + a b a .
The overunderset is one way around the problem using by containing the over- and under- positions for symbols:
1234567890 + b a c + 1234567890 + b a c + 1234567890
1234567890 + b a c ,
1234567890 + b a c .
Reduction to overset [ edit ]
With the under
parameter empty:
1234567890 + b a + 1234567890 + b a + 1234567890
1234567890 + b a ,
1234567890 + b a .
Reduction to underset [ edit ]
With the over
parameter empty:
1234567890 + a b + 1234567890 + a b + 1234567890
1234567890 + a b ,
1234567890 + a b .
