逐字环境中的分数

首先：这是一个类似于这里。

如何在绿色框中写入分数作为输出？

分数应该出现在之后，2类似于的输出\frac{3}{5}但像素化，无论是在显示的输入（绿屏，左）还是显示的输出（绿屏，右）。

可取但不必要：分子高度应为 5 像素，然后是 1 像素空白，然后是 1 水平线作为描边，然后是 1 像素空白，然后分母高度应为 5 像素。此外，分数应相对于分数前面的数字垂直居中。

答案1

不确定我是否真的理解\textLCD宏的工作方式，但使用一种非常手动的方法（还有什么）堆叠，我能够（希望）做一些类似于期望的事情。

修订的解决方案

我最初有\pixelfrac{NUMERATOR}{DENOMINATOR}可以创建分数的，但我仍然必须使用堆栈将其覆盖在该行的其他内容上。现在，我发现我能够将宏（无参数）内联插入到中\textLCD。但是，要使用此功能，我必须\pixelfrac在之前调用（带参数）\textLCD并让它将的内容保存\pixelfrac到没有参数的宏中。然后我可以在的参数中使用该无参数宏\textLCD。

然后我发现我需要使用零宽度，\pixelfrac这对 的水平间距有影响\textLCD。因此，我必须以以下\pixelfrac形式添加一个额外的参数

\pixelfrac{NUMERATOR}{DENOMINATOR}{EVENTUAL COLUMN PLACEMENT}

这样\pixelfrac就可以在盒子中填充适当的空间，使其出现在所需的位置。

因此，在下面的 MWE 中，像素化构造的核心是：

   \pixelfrac{3}{5}{2}%
   \pixelfrac[\thefracB]{1}{5}{18}%
   \textLCD[0]{18}|2\thefrac*|
   \textLCD[0]{18}|                5\thefracB|}

这表示默认宏\thefrac应将分数 3/5 放入第 2 列，\thefracB将 1/5 放入第 18 列。
