Usage of "%" in an equation

[dominic...@springer.com]

recently I come across an equation

$$\text{E=}\frac{\text{A <1mm}}{\text{B}}\text{in}\text{\% }$$

and MathJax displays as

Refer the "\" before "%". I am aware that the "%" is present inside \text. Just wondering it is right to show the "\" symbol in MathJax view. If I remove "\" then the rest of the Tex equation become a comment and may be invalid. How do you handle such situation?

Regards

Hi,

This is expected behavior. MathJax does not process macros in \text{} except to identify mathematics within it.

See https://github.com/mathjax/MathJax/issues/1473 for more discussion and links.

Regards,

Peter.

Following up on Peter's comment that MathJax doesn't process macros in text mode, it also doesn't process comments in text mode, so \text{% } does cause a comment, and will generate the correct output for you.  On the other hand, so would "\%\space" or "\%\text{ }" rather than "\text{\% }" if you want to keep something that will work in both MathJax and actual TeX.
