Store \pgfmathresult in a variable

The result of `\pgfmathparse` is automatically stored in `\pgfmathresult`. Is it possible to store it in an other variable, too?

-

Use `\pgfmathsetmacro\mymacro{...}` instead of `\pgfmathparse{...}`.

From the v2.10 `pgfmanual`, section 62.1 Commands for Parsing Expressions, page 527:

`\pgfmathsetmacro{<macro>}{<expression>}`
Defines `<macro>` as the value of `<expression>`. The result is a decimal without units.

`\pgfmathsetlengthmacro{<macro>}{<expression>}`
Defines `<macro>` as the value of `<expression>` LaTeX in points.

`\pgfmathtruncatemacro{<macro>}{<expression>}`
Defines `<macro>` as the truncated value of `<expression>`.

In theory you could also say `\let\mymacro\pgfmathresult`, but I recommend the above macros.

-
``````\edef\myvar{\pgfmathresult}
when the value from `\pgfmathparse` has been computed. Or `\xdef` instead of `\edef` if you need it globally, i.e., outside the TiKZ environment in which the computation is performed.
Note that `\pgfmathresult` is already fully expand, so I would prefer `\let\myvar\pgfmathresult`, with `\global` as prefix if required. –  Martin Scharrer May 21 '11 at 22:45
No. Adding `\global` in front of them shouldn't work. –  Martin Scharrer May 21 '11 at 23:01
