I've coded more than one mini-big int libraries for some high school CS comps back in the day. Also fun times. Simple arithmetic is easy and we never got really complicated operations for big ints. These days I'm super lazy and just Python the big int problems on things like Advent of Code. Much more boring. And because of floating point issues, I haven't seen them give something in the real domain, as compared to whole numbers.
