bm 和 siunitx 不匹配

Question

有了這個mwe，

\documentclass{article}
\usepackage{bm,siunitx}

% change nothing to the problem
\sisetup{
    detect-weight,
    detect-display-math
}

\begin{document}
$\bm{\num{.1}}$
\end{document}

我收到此錯誤訊息

> ! Undefined control sequence.
> <argument> \LaTeX3 error: 
                A sequence was misused.
l.11 $0<\bm{\num{.1}}
                   $

有了另一個 mwe ：

\documentclass{article}
\usepackage{siunitx,bm}

\sisetup{
    detect-weight,
    detect-display-math,
    detect-inline-weight=math
}

\begin{document}
$\num{5}x\bm{5x\num{5}}$
\end{document}

我有下一條錯誤訊息：

! Argument of \__tl_tmp:w has an extra }.
<inserted text> 
\par 
l.11 $\num{5}x\bm{5x\num{5}}
                      $

並且\mathbf不起作用並且會產生醜陋的“x”。

\documentclass{article}
\usepackage{siunitx,bm}

\sisetup{
    detect-weight,
    detect-display-math,
    detect-inline-weight=math
}

\begin{document}
$\num{5}x\mathbf{5x\num{5}}$

$\bm{0.1}\quad\mathbf{\num{.1}}$
\end{document}

Answer 1

您可以用大括號保護\num和\SI指令：

\documentclass{article}
\usepackage{bm,siunitx}

\begin{document}


\sisetup{detect-weight = true,detect-inline-weight = math}

$\num{5} \SI{50}{\km}$

$\bm{bob{\num{5}\SI{30}{\km}}}$
\end{document}
