| Feb 11, 2013 at 15:24 | comment | added | Habi | @Rasoul Yes, exactly. I'm using it like \x+78+\shadow in the fifth line from bottom. Dividing works too. Try changing said line to \draw[|-|,white,thick] (\x/2,\y) -- (\x/2+78,\y) node [midway,above] {\SI{500}{\micro\meter}}; and you see that the white scalebar moves... | |
| Feb 10, 2013 at 19:00 | comment | added | Rasoul | Then, how we can use the defined variable somewhere else where we need to divide it by, for example, 2? \varname/2? \varname*0.5? | |
| Oct 26, 2012 at 6:50 | comment | added | Habi | You're of course right that the answer could be written much shorter, but I wanted to show a full example on how I use \dev\varname{initialValue}. | |
| Oct 25, 2012 at 17:49 | comment | added | bobobobo | Yes, so to be clear your answer is \def\varname{initialValue}. I think your example is far too complicated to show use of a simple variable. | |
