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 the non-oriented integrals \oiint and \oiiint which are not yet rendered on OODA WIKI.
Arguments
- preintegral the text or formula immediately before the integral
- symbol the integral symbol,

- intsubscpt the subscript below the integral
- integrand the text or formula immediately after the formula
All parameters are optional.
