Package siunitx Error: Invalid number '1.654 x 2.34 x 3.430'

Question

when I tried to render the document in texlive 2023 with xelatex compiler:

\documentclass{article}

\usepackage{siunitx}

\begin{document}

\begin{center}
    \num{.3e45}\\
    \num{1.654 x 2.34 x 3.430}\\
    \si{\kilogram\metre\per\second}\\    
    \SIlist{0.13;0.67;0.80}{\milli\metre}
\end{center}

\end{document}

shows error:

! Package siunitx Error: Invalid number '1.654 x 2.34 x 3.430'.

what should I do to fixed this issue? I have tried to tweak to * but still did not fixed this issue:

! Package siunitx Error: Invalid number '1.654 * 2.34 * 3.430'.

Answer 1

You will have v3 of siunitx which in contrast to v2 doesn't support products in \num. You need to use \numproduct for these cases:

\numproduct{1.654 x 2.34 x 3.430}
