Mathjax逗号数字 [英] mathjax commas in digits

问题描述

这是TeX的遗留问题-在需要空格时更需要空格:12,123可能是数字，而12, 123可能是列表. las，就是这样.

This is a TeX legacy issue---it would have made more sense to require a whitespace when a whitespace is desired: 12,123 is probably a number, while 12, 123 is probably a list. Alas, it is what it is.

与数字中的逗号的MathJax渲染有关，解决方法是通过{,}抑制空格.可行，但不方便.有没有办法使它自动执行?

Related to MathJax rendering of commas in numbers, where the solution is suppression of spaces via {,}. Works, but inconvenient. Is there a way to make this automatic?

https://github.com/mathjax/MathJax/issue/169#issuecomment-2040235 与欧洲诉盎格鲁之争有关.等价的骇客，

The hack in https://github.com/mathjax/MathJax/issues/169#issuecomment-2040235 is concerned with European vs Anglo. The equivalent hack,

<script type="text/x-mathjax-config">
  MathJax.Hub.Register.StartupHook("TeX Jax Ready",function () {
    MathJax.InputJax.TeX.Definitions.number =
      /^(?:[0-9]+(?:\,[0-9]{3})*(?:\{\.\}[0-9]*)*|\{\.\}[0-9]+)/
  });
</script>

解决了1,234.56中的逗号问题，但是句点之后(即5之前)现在有一个空格.我不确定上面的正则表达式如何工作.有人可以帮忙吗?

solves the comma problem in 1,234.56 but now there is a space after the period (i.e., before 5). I am not sure how the regex above works. can someone help?

推荐答案

将模式更改为

/^(?:[0-9]+(?:,[0-9]{3})*(?:\.[0-9]*)*|\.[0-9]+)/

允许将12,345.6视为数字，而12, 345是两个数字的列表.在原始模式中，\{\.\}需要文字{.}(包括花括号)，而不仅仅是十进制.

to allow 12,345.6 to be treated as a number, while 12, 345 is a list of two numbers. In the original pattern, the \{\.\} requires a literal {.} (braces included), not just a decimal.
