Template:Overunderset
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:
- the first parameter is the main symbol,
- the second parameter is the symbol above the main symbol,
- 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 + + 1234567890 + + 1234567890
but sometimes one combination will not work, particularly when there is only one combined application of templates on a line:
- 1234567890 + ,
- 1234567890 +
The overunderset is one way around the problem using by containing the over- and under- positions for symbols:
- 1234567890 + + 1234567890 + + 1234567890
- 1234567890 + ,
- 1234567890 + .
Reduction to overset
With the third parameter empty:
- 1234567890 + + 1234567890 + + 1234567890
- 1234567890 + ,
- 1234567890 + .
Reduction to underset
With the second parameter empty:
- 1234567890 + + 1234567890 + + 1234567890
- 1234567890 + ,
- 1234567890 + .
