我希望能够为我的问题添加半分，但我不知道如何处理\stepcounter。下面是我的样式文件的一部分，您能帮忙吗？我本质上想说\mrks{0.5}，并且必须将这些添加到打印在问题顶部的总分中，由我的\question{}命令定义。

编辑 老实说，我发布的样式文件不是我写的。这是几年前别人写的，我们联系不上他。我真的很想实现 David 的建议，但这超出了我对乳胶的理解和经验。我很想学习低级乳胶编码，但由于时间有限，我负担不起。任何针对我提交的样式文件更具体的建议都将非常受欢迎。
答案1
您的最小示例实际上并不接近最小示例，因此我没有使用它。TeX 计数器是整数，因此您可以选择保留 10 倍的标记并在.打印时添加，或者像这里一样使用长度寄存器并pt在末尾删除。
