while reading a book on maths lately, I have seen a small integral delimiter such that, in what follows:
\begin{equation}
\sum_i^j A_{ij}\int\limits_{-\infty}^{+\infty} \cos x dx
\end{equation}
the sum and integral would be of the same height. Are you aware of something like that?
Thank you

With an up-to-date texlive-2010, if you use Asana Math font with
unicode-math
package (requires XeTeX or LuaTeX), you will get an integral that as high as the summation symbol:
