Symbols:Bar/Technical Note

Technical Note for bar symbol

The $\LaTeX$ code for \(\bar {x}\) is \bar {x}  or \overline {x}.

When either of the arguments is a single character, it is usual to omit the braces:

\bar x or \overline x

Note that \overline x is preferred on $\mathsf{Pr} \infty \mathsf{fWiki}$, as it expands to cover the entire argument.

Compare:

$\bar \omega$, produced by \bar \omega

with:

$\overline \omega$, produced by \overline \omega.
