Long Bars in Latex

[jinydu]

When making Latex documents in WinEdit, I've been using \bar{expression}. The trouble is, this only prints a short bar above the center of the expression. So unless I have a very short expression (1 or 2 characters), it looks like most of the expression is not under the bar.

Is there some command to make a bar that is as long as the entire expression?

Thanks

\overline{expression}:

It works, thanks

Perhaps \bar was intended for use only above single characters. A search on "bar" in Eric Weisstein's World of Physics (http://scienceworld.wolfram.com/sear...Fphysics&q=bar) finds several examples, such as \bar E and \bar N at http://scienceworld.wolfram.com/phys...lEnsemble.html
