Tikz 和科学计数法

Question

我想用 Tikz 绘制类似这样的内容：

\tikzstyle{every picture}+=[remember picture]
\everymath{\displaystyle}\begin{equation*}
{\huge
    \tikz[baseline]{
        \node[fill=blue!10] (n171)
        {$0,000$};
    }
    \tikz[baseline]{
        \node[fill=blue!20] (n172)
        {$7$};
    }
    \tikz[baseline]{
        \node[fill=blue!30] (n173)
        {$82$};
            }
    \tikz[baseline]{
        \node[fill=blue!40] (n174)
        {$0 $};
    } \quad \Longrightarrow \quad
    \tikz[baseline]{
        \node[fill=blue!10,anchor=base] (t172)
        {$7$};
    },
    \tikz[baseline]{
        \node[fill=blue!20,anchor=base] (t173)
        {$82$};
    } \cdot
    \tikz[baseline]{
        \node[fill=blue!30,anchor=base] (t174)
        {$\num{e-4}$};
}
}
\end{equation*}\begin{tikzpicture}[overlay]
    \path[->] (n172) edge [out=90, in=90] (t172);
    \path[->] (n173) edge [out=-90, in=-90] (t173);
\end{tikzpicture}

有没有更好的办法？谢谢

Answer 1

我已尝试了@Symbol 1 给出的指示，这就是我所取得的成果。再次感谢。
