# [Tex/LaTex] How to denote the standard deviation with siunitx

siunitx

I'm certain that I saw a command generating the following kind of output the last time I read through the siunitx manual:

\left( 12.3 \pm 0.4 \right) V


for a measured voltage of 12.3 V and a standard deviation of 0.4 V. I can't find it by searching the manual, though. Is this capability in siunitx?

The code you are looking for is on page 43 of the siunitx manual (as of 2011/10/14):
\sisetup{separate-uncertainty}%
