I like Rust but I’m constantly surprised by how hard simple math involving subtraction and or division is, and how there’s little to no advice in the docs about best practices. The math code ends up being littered with `as another-number-type` and the builtin operators are almost never what you need (instead I need to use saturating_ methods etc.). I want my code to handle overflows and precision errors, but I would like to spend less time figuring out how to do it.
