Other SEs can format mathematical formulas in a way called mathjax. It makes fractions and equations and pretty much everything mathematical look good.
It's a subset of tex for the internet and it makes those formulas (as ugly as their content may be) look rather pretty. (that is, the prettiness of typeset text)
I agree that this is not the most important thing, because formulas only show up occasionally in photography, but they still do show up from time to time.
It shouldn't be hard to implement either, because the functionality already exists.
Here are some example posts in which I wanted to use it and which in turn caused me to ask this question here:
- This question involves optical formulas. This seems to be the most obvious use case, because photography is in part applied physics.
This great question about different terms used by different manufacturers could benefit from using tables, ...(Edit: Markdown tables were implemented in 2020 (c.f, scottbb's answer below).
If MathJax were enabled for Photo-SE, the standard delimiter of
$ ... $ would be an issue (because we often mention gear prices), so we could instead use delimiters of
\$ ... \$ for inline MathJax. (The
$$ ... $$ block-level MathJax delimiters is fixed).
