Thank you, *so* much.

Mixed numbers don't exist in some countries. If you use them in written form, some people may not understand them at all.

Just watched an episode of MacGyver - they had a Lat/Long as part of the plot, and the location they claimed it was is *nothing* like it is in real life.

That's a bit of a disappointment, and given the nature of the show, they *must* know *someone* will check.

For other people running my MathJax patch, here's a commit that adds MathJax (and the plaintext TeX → unicode auto-replacement) into Mastodon 3.0.0: github.com/tootsuite/mastodon/

A Mastodon instance for maths people. The kind of people who make $$\pi z^2 \times a$$ jokes. Use $$ and $$ for inline LaTeX, and $ and $ for display mode.
