pgfmathtruncatemacro 疯了

这真的很奇怪。当我用 pgfmathtruncatemacro 定义距离时，它通常有效，但有一个不起作用并且没有意义。如果距离的名称被实数覆盖，它就会起作用。但这只发生在一个距离上，无论你使用什么名称。这是代码：

我认为计算是使用pt“单位”进行的，因此 1mm 转换为点。因此，

\pgfmathtruncatemacro{\patitas}{1mm}

保持\patitas值 2，因为 1mm 大约为 2.8pt。同样注意，\pgfmathtruncatemacro \noded {1 cm}实际上会\noded扩展到 28。

如果你想创建一个保存长度的宏，你可以使用

\newcommand\patitas{1mm}

或者如果你需要进行计算，请使用

\pgfmathsetlengthmacro\patitas{1mm}

如果您这样做，您还会得到更符合预期的东西++ (left:\patitas pt)，请注意pt，但由于truncate，距离将约为 0.7 毫米而不是 1 毫米。
