Template:Oiiint
This template is used to include the double closed integral, usually in a mathematical formula. It overcomes a limitation of the TeX rendering which cannot display this symbol without clumsy workarounds.
This template was ported from Wikipedia.org.
Arguments
- preintegral the text or formula immediately before the integral
- intsubscpt the subscript below the integral
- integrand the text or formula immediately after the formula
All parameters are optional.
Examples
- Two of Maxwell's equations, e.g. the Maxwell–Faraday equation and Ampère's circuital law (with Maxwell's addition).

Technical details
The \oiint command is not part of AMS-LaTeX, and thus not part of the math support that MediaWiki provides. It is available as a unicode character U+222F ∯ but font support for this character can be lacking. For this reason, the template provides an image variant of the character.
