How to add \= ("macron", "overbar") in an equation?
2,972
In general text accent commands uses symbol names: \=
for macron \"
for umlaut etc, and math accents (which are logically quite distinct) use words so \bar
for an over bar accent, and \ddot
for a double dot accent, etc. In the case of the bar sometimes \overline
works better (that is not built using the math accent primitives, but is simply a rule drawn over the expression, but unlike \bar
which is a fixed character from the font, \overline
extends as needed to cover the expression.

I am trying the following code
\begin{equation} \bm{F}=\bm{F}_{vol}\={\bm{F}} \end{equation}
But it's some errors. I think the error might be because I cannot use macron in math environment. how can I resolve this?

egreg almost 6 yearsWhat is
\=
supposed to produce? Are you perhaps looking for\bar
? -
David Carlisle almost 6 yearsprobably you want
\bar
or\overline

barbara beeton almost 6 yearsthere is no overlap between diacritics for text and those for math, but for the ones common in math, there are parallel versions. the macron equivalent for math is
\bar
.
