Unlucky - but that wasn't a easy one at all, just too many possibilities.

ESP32 floating point performance[^]
I didn't consider the ESP32's abysmal FPU when I designed htcw_gfx[^]
I figured for maintainability, and just because this library primarily is for 32-bit CPUs that I could rely on floating point math rather than scaled integers for doing my computations.
It doesn't even have multiplication or division entirely in hardware. It has to be done partially in software. *headdesk*
Ultimately this is my fault. I should have done my legwork. Now I'm kicking myself.

Well, kicking yourself seems like good leg work.
|
|

You mean homework.
Years ago in grad school we were assigned a project to implement floating point division and multiplication in micro-code (binary assembly code). It was a bear. So many steps. The lesson was the difference in hardware and software implementations was tremendous. Over the years, some vendors have kept these specs blurry, so you are not alone.

"legwork" works in this case too. It's an idiom that comes from "detective work" for when cops would investigate, because they have to chase down leads, sometimes go door to door etc, hence using their legs.
I should have investigated the FPU performance on major platforms before I made the decision to go with floating point.

Ah so. You are right. Besides standing on the corner, another reason for the slang word "flatfoot" for cops.

"flatfoot" comes from the number of policemen developing fallen arches in their feet from being on the beat, not just standing on the corner.
Iβve given up trying to be calm. However, I am open to feeling slightly less agitated.

I know. An old negative slang word.
Standing, walking, sitting, you name it.
I have 3 cousins and 2 nephews who are policemen.
There is also back issues and stress at home. Hard job.
They all work hard to stay in shape.

I have some experience in heavy optimization, obviously not the amount you have, but the very first thing I learn is "Floating point: just say no". Fixed point (aka scaled integer arithmetics) is king both for performance and for precision management: while it's true that on average it's less precise than floating point, if the problem has defined or definable boundaries it has the advantage of keeping the same precision on the whole domain.
For engineering purposes it's much more valuable than floating points, for scientific purposes where speed and throughput are tertiary floating wins.

That used to be true, but actually on processors like the ARM Cortex-M used in the Teensy 4.1 it has a remarkable little FPU. It does 32-bit FP in the same number of cycles it does a 32-bit int (although there are additional optimizations for ints)
That's why I wrote my code for maintainability. In retrospect, it was a mistake. I made an incorrect assumption about the average capabilities of FPUs on these little 32-bit systems.

The other day I utilized WinZip and found on Edge::News::My Feed an ad and a large one at that the next day for just that product. Even more amazing to me I just now enjoyed much of a tasty bag of Cheetos my favorite item in the food pyramid except of course stale potato chips and upon viewing Edge::News::My Feed I see an ad for Chester's Popcorn. Haven't found the cameras yet.
