[Tex/LaTex] How to write 7.5 ( ± 2.5) × 10 − 5 in siunitx

Question

I can seem to find a question like this one, but maybe I don't know how to properly describe it, so sorry if it has already been answered.

I am using siunitx but I want to put my range in parentheses after the value but before the exponential as in the title.

I tried 7.5 ($\pm$ 2.5)\num{e-5} but that does not give you the correct format.

Any ideas would be much appreciated.

Thanks

Answer 1

You should write

\num[separate-uncertainty]{7.5(25)e-5}

to obtain

MWE

\documentclass{report}

\usepackage{siunitx}

\begin{document}

\num[separate-uncertainty]{7.5(25)e-5}

\end{document}
