Add gradians, degrees/minutes/seconds support. #4

alexbarry · 2024-06-03T17:39:11Z

change angle mode button (radians/degrees) to show current state, rather than show state to switch to if pressed
add gradians angle mode
add degrees/minutes/seconds handling
add degrees/minutes/seconds button to HTML version

minor:

wrap LaTeX output in \text{} only if non numeric.
round trig functions' output if less than 1e-15 (so sin(2*pi) gives 0, not 1e-16 ish)

Note: now the HTML UI button indicates the current angle mode state, rather than the state that you will be brought to if you press it. TODO: add a warning to the UIs about this.

This prevents sin(2*pi) or sin(180 degrees) from returning 1e-16 something. I am probably missing some more of these with complex math, but this is a good start.

I still need to add the LaTeX handling of this

This way you can print the type of a node when debugging.

This way, instead of seeing "\text{123}" in the LaTeX, you'll see only "123". The main motivation for this was adding degrees, since those are numeric-ish and wouldn't render inside a "\text{}".

Otherwise the process seems to remain running, potentially consuming a bunch of ram if you mess up the regexes and get stuck in an infinite loop...

Including fixing a really bad bug where the "within difference" function wasn't taking the absolute value, causing a bunch of clearly wrong tests to pass.
