siunitx displaying wrong uncertainty values for integers

Question

I am getting incorrect uncertainties displayed for integer-valued numbers using the siunitx package. It seems to insert one decimal place and divide the uncertainty I specify by 10.

This is a new problem since upgrading to the 2014-09-29 package version.

\documentclass{article}

\usepackage{siunitx} 
\sisetup{separate-uncertainty = true} % use +/- symbol for uncertainty values

\begin{document}

Using integers, 

\verb+\num{30 \pm 2}+ gives \num{30 \pm 2}

but I want the value to appear as \num{30} 

and the uncertainty should be \num{\pm 2} with no decimal parts.

Same problem happens using \verb+\SI+ and in tables using S-columns.

Things seem to work fine if the base value is not an integer:

\verb+\num{30.5 \pm 2}+ gives \num{30.5 \pm 2}

\end{document}

Answer 1

Try it with:

\num{30(2)}

This works for me, if I only change the uncertainty in the \num command.
