If you've ever wrestled with fixed-point math, scaling, and rounding, this blog post is for you!

I go deeper into binary arithmetic, division tricks, rounding, and what it really takes to build fixed-point systems that work.

As always, I appreciate all of your feedback and corrections.

Ah, the dream of surviving the #apocalypse with only a pocketful of Forth code and a prayer . Collapse OS promises to keep the lights on (if you still have any) by running on contraptions MacGyver would envy. Because, you know, nothing eases the end of civilization quite like compiling assembler source on your potato-powered microcontroller.
