you have to remember 11 33 55 and put the bar in the middle. It is mainly small MCU like ATMEGA and co. lacking FPU, and yes old stuff like Z80 ,6502, etc.
Not a lot, and this is why to speedup thing on some architecture, when working with (unsigned)integer you multiply by 355 then divide by 113 (it’s like 3.14159292035)
What do you define as nuclear power? Because something like Pioneer 10 which is in space since 1972, is using a nuclear reactor to provide its power, and it is still working.
