  Surprised me as well janestreet are a well known user of ocaml and I can't imagine they don't use a lot of floats.

  I guess it is the typical complain about using separate operators for ints and floats. It never bothered me in Caml Light, let alone when Objective Caml was introduced.

    Ah, maybe, perhaps I am in the minority that liked the different operators for ints and floats. :D

    You can write floating point operators in several different ways. You can write with the normal floating point operators x *. y +. z or, since `Float.(+) = (+.)`, `Float.() = (.)`, etc, let open Float in x * y + z or simply Float.(x * y + z)

      That is pretty neat. Does it mean that one could do something similar for vectors and quaternions? let open Quaternion in x * y + x

        Yes.
      • andrepd 8y ago
        Yep. You could write module Quaternion = struct let (+) = ... let ( * ) = ... end then let open Quaternion in imports the contents of Quaternion into local scope, so you can write x * y + z

  Symbols (variants with our without parameters) and integers are unboxed, while floats are not (but in a few specific cases such as arrays of floats, and iiuc that's an inelegant special case on its way out, as it prevents other optimisations).
