which package for \oiint symbol

Question

I have some code which uses the \oiint symbol. However there are many packages that provide this command. Most of for special fonts. I am using lmodern however and want a package that provides the symbol matching to lmodern.

I have found so far wasysym with option [integrals], mathabx and esint package.

Answer 1

If I go to the detexify site and draw the double-integral-with-circle symbol, the answer I get is \oiint from the esint package. The package also provides the command \varoiint for a perfectly circular-shaped circle symbol. (Sounds rather circular, doesn't it?!)
