# Enhanced \oint to emphasize circulation

I'm looking for a symbol that merges \iint and \oint together (a dedicated package, if it could exist, would provide something like \oiint and \oiiint).

The purpose of \oint is to show that the integration path is closed (it is often used in the definition of the circulation), but the adding one (or two) more integral it is emphasized that the integral is calculated over a surface (\oiint) or over a volume (\oiiint).

Do these symbols exist in the world of LaTeX?

• The unicode-math package also provides these, though it also messes with other math commands. – jvriesem May 12 '16 at 21:46
Using \oiint \hspace{-13.5pt} \int I was able to create an \oiiint replacement. It uses the \oiint from the esint library. (\usepackage{esint})
• So how does this scale when using 10pt, 11pt or 12pt document class option? – Werner Dec 5 '17 at 0:53
