    Float processing is at the hardware level. It needs a way to signal when an unrepresented value would be returned.

      My thinking is that a call to the safe division method would check after the division, whether the result is a NaN. And if it is, then it returns an Error-value, which you can handle.

      Obviously, you could do the same with a NaN by just throwing an if-else after any division statement, but I would like to enforce it in the type system that this check is done.

        I feel like that’s adding overhead to every operation to catch the few operations that could result in a nan.

        But I guess you could provide alternative safe versions of float operations to account for this. Which may be what you meant thinking about it lol

          I would want the safe version to be the default, but yeah, both should exist. 🙃
