Still it does not sit right with me - it might work, but figuring out the math with fixed point is not that hard, just requires some sitting down and thinking about it.
It's like I have some light fixtures in my attic that are connected with wires twisted together and covered with electrical tape - they certainly work and have done for a decade, but its still not right and I wouldn't recommend anyone do it this way.
Exactly, it's a very nice alternative to searching the web and discovering new stuff.

I used to think like you. But then I realized the Atmega 328p is running at 16 MHz, so even hundreds of . As you can see here[1], it can do 94k double-precision FLOPS, more than enough for simple sketches like this. This jives with the benchmarks I did several years ago.
Sure if I was writing some tight control loop or similar I wouldn't use floating point.
