I'm trying to write in bold some numbers expressed in scientific notation (using \num).
What I've been trying is:
\usepackage{siunitx}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amssymb}
\textbf{\num{1.34e+2}}
$\mathbf{\num{1.34e+2}}$
but none of them seems to work.
How can I do that?
You can use text-series-to-math and propagate-math-font to make siunitx use the font series from the surrounding material.
\documentclass{article}
\usepackage{siunitx}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amssymb}
\sisetup{
text-series-to-math = true ,
propagate-math-font = true
}
\begin{document}
\textbf{\num{1.34e+2}}
$\mathbf{\num{1.34e+2}}$
\end{document}
Without updating siunitx, it can be done in the following way:
\num[math-rm=\mathbf]{1.34e+2}
