Macros for convenient maths with checked, wrapping or saturating semantics

Macromath provides macros which allow to perform checked, wrapping or saturating math using regular operators (+-*/%).

use macromath::checked;

fn calc() -> Option<i8> {
  Some(100)
}

assert_eq!(Some(50), checked!(calc()? / 2));
assert_eq!(None, checked!(3u32 - 9u32 / 4 * 2));
