Interesting! I have been using integers or f32 for that. What was the use case specifically? Did you write a software float for it? I remember writing a `f16` type for an IC that used that was a pain!

Tight memory constraint. I was putting configuration somewhere it shouldn't have been, but it meant we didn't need to buy an extra chip.

Yes, purely software.
