# Inline Math in Display Mode

I know how to have inline math typeset as in display mode in LaTeX, i.e summations with the index below the sigma, but I'm trying to learn ConTeXt and cannot figure out how to do it.

Any thoughts? Is there a way to do it in ConTeXt?

$\displaystyle\sum_{i=1}^n a_i$
$\sum\limits_{i=1}^n a_i$
