# To have two limits in double integral?

My tex

$$\iint \limits_{-\infty}^{+\infty}$$


It looks like

I want two limits there above and below.

How can you have two limits above and below the two integrals?

How 'bout just using \int twice? – Steven B. Segletes Dec 5 '13 at 14:44

You are probably expecting iterated integral, not double integral. Hence

\documentclass{article}

\begin{document}

\newcommand{\Int}{\int\limits}

$$\Int_{-\infty}^{+\infty} \Int_{-\infty}^{+\infty}f(x,y) \,dxdy$$

\end{document}
