This template is used to include the oriented integrals around closed surfaces (or hypersurfaces in higher dimensions), usually in a mathematical formula. They are additional symbols to \oiint and \oiiint which are not yet rendered on Wikipedia.
Arguments
- preintegral the text or formula immediately before the integral
- symbol the integral symbol,

orientationoint=x45px oiint=x45px oiiint=x45px varoint=x45px varoiint=x45px varoiiint=x45px Counterclockwise

- The default is x45px
- intsubscpt the subscript below the integral
- integrand the text or formula immediately after the formula
All parameters are optional.
Examples
- The work done in a thermodynamic cycle on an indicator diagram: <math>W=</math> x44px<math>{\scriptstyle \Gamma}</math> <math>p{\rm d}V</math>
