是否有类似 \italicmath 的命令？

一个众所周知的命令是\boldmath（相当于\mathversion{bold}），它使所有数学符号变为粗体。是否有类似的斜体数学命令，其工作原理与 类似\mathit，它使所有数学符号（包括数字) 斜体在当前块结构中。它应该像下面的 M-non-WE 一样工作。

对我来说，使用\mathit不是解决方案，因为如上所述，我想要一些适合的东西，全部当前区块中的数学。根据本指南，没有\mathversion{italic}。

\documentclass{memoir}%it must work with memoir, so no solutions with \it allowed.

\newcommand\italicmath{
   %Do magic for me.
}

\begin{document}

Normal math, with upright numbers: $x = 123$.

{\italicmath Italic math, with italic numbers: $x = 123$.}

{\boldmath\italicmath Italic bold math, with italic bold numbers: $x = 123$.}

\end{document}

在此处输入图片描述

\documentclass{memoir}%it must work with memoir, so no solutions with \it allowed.

\newcommand\italicmath{\mathversion{italic}}
\newcommand\bitalicmath{\mathversion{bitalic}}

\DeclareMathVersion{italic}
\SetSymbolFont{operators}{italic}{OT1}{cmr} {m}{it}
\SetSymbolFont{letters}  {italic}{OML}{cmm} {m}{it}
\SetSymbolFont{symbols}  {italic}{OMS}{cmsy}{m}{n}
\SetMathAlphabet\mathsf{italic}{OT1}{cmss}{m}{sl}
\SetMathAlphabet\mathit{italic}{OT1}{cmr}{m}{it}
