在下面的例子中，我希望生成的 pdf 显示300和的值500，但它们不会打印。
\documentclass{article}
\begin{document}
\newcounter{fund}
\newcommand{\fund}[1]{\addtocounter{fund}{#1}}
My first funding was worth \$\fund{300}.
My second funding was worth \$\fund{500}.
Thus, in total, my funding was \$\thefund.
\end{document}
有没有办法可以打印此值而不需要冗余：
My first funding was worth \$300. \fund{300}
谢谢。

我不确定这是否意味着（并且无论如何我也不推荐这样做），但是这里是\fund添加增量值并打印fund计数器的这个值的定义。
\documentclass{article}
\newcounter{fund}
\newcommand{\fund}[1]{\addtocounter{fund}{#1}#1}
\begin{document}
My first funding was worth \$\fund{300}.
My second funding was worth \$\fund{500}.
Thus, in total, my funding was \$\thefund.
\end{document}
更新
这是一个略有不同的版本：
\documentclass{article}
\newcounter{incfund}
\renewcommand{\theincfund}{\textdollar{}\arabic{incfund}}
\newcounter{fund}
\newcommand{\fund}[1]{%
\setcounter{incfund}{#1}\theincfund%
\addtocounter{fund}{#1}%
}
\begin{document}
My first funding was worth \fund{300}.
My second funding was worth \fund{500}.
Thus, in total, my funding was \textdollar\thefund.
\end{document}
