vertical ' = ' symbol

[pkg]

Dear all,

is there in LaTeX a ' = ' symbol (equal symbol) which is rotated by
90° ... I need it to create a commutative diagram like picture in
pstricks ... maybe there is a suitbale rotation command which I can
apply to the original = symbol?
By the way: \| is no alternative, because I want the symbol to have
exactly the same length as = and I do not want the amscd package (which
provides some vertical double lines) either!
Many thanks

\newcommand{\verteq}[0]{\begin{turn}{90} $=$\end{turn}}

If you place this in the top of your document or in your preamble
you should be able to write \verteq and get your vertical equal sign.
There are probably other and better ways to do this - but I think it
will work.

YUP :) I just tested it, and it works perfectly (Just remember that the
command "turn" does not work correctly in WhizzyTeX - which is my best
LaTeX tool)

Dear Per
the environment turn is unknown to my MiKTeX ... which package is
require to make it known?

it's part of the rotating package.

however, the graphics/x package(s) provide a rotatebox command which
would do just as well (and require one package fewer):

\usepackage{graphicx}
...
\rotatebox{90}{$=$}

however, given that you're using pstricks, there's (almost certainly)
a rotation command that would swim well with what you have already, as
part of some pstricks package.

\rotateleft{=}

OK ... I have found another solution quite similar to yours:

\usepackage{rotating}

\begin{rotate}{90}=\end{rotate}

@Robin Fairbairns: didn't see your post appearing while writing my post
... os it's no longer
"another" solution ...

I see you found the package :)...

\begin{rotate}{90}=\end{rotate}

the rest was just a newcommand, so you do not need to write too much
every time you need your vertical =

Better than {turn} is to use the standard graphics command
\rotatebox (package graphics or graphicx).

However, you should beware that rotation is not really
supported by TeX, and relies on downstream output drivers.

I don't know if some math symbols package has a pre-rotated
equals sign.

There is $\parallel$, which looks a bit long, and amssymb has
$\shortparallel$, which looks a bit short.

This has the advantage of being adjustable:
\rule[.4ex]{.4pt}{1.6ex}\hspace{2pt}\rule[.4ex]{.4pt}{1.6ex}
