Module Core_kernel__.Sign

This module extends Base.Sign with bin_io.

type t = Base.Sign.t =
| Neg
| Zero
| Pos
include sig ... end
val typerep_of_t : t Typerep_lib.Std.Typerep.t
val typename_of_t : t Typerep_lib.Std.Typename.t
include module type of Base.Sign with type Sign.t := t

A simple type for representing the sign of a numeric value.

type t = Base__.Sign0.t =
| Neg
| Zero
| Pos
include sig ... end
val all : t list
val hash_fold_t : Base.Hash.state ‑> t ‑> Base.Hash.state
val hash : t ‑> Base.Hash.hash_value

This provides to_string/of_string, sexp conversion, Map, Hashtbl, etc.

val (<) : t ‑> t ‑> bool
val (<>) : t ‑> t ‑> bool
val equal : t ‑> t ‑> bool
val compare : t ‑> t ‑> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t ‑> t ‑> t
val max : t ‑> t ‑> t
val ascending : t ‑> t ‑> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~cmp:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t ‑> t ‑> int
val between : t ‑> low:t ‑> high:t ‑> bool
val clamp_exn : t ‑> min:t ‑> max:t ‑> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

type t
val pp : Caml.Format.formatter ‑> t ‑> unit
val of_int : int ‑> t
val to_int : t ‑> int

Map Neg/Zero/Pos to -1/0/1 respectively.

val to_float : t ‑> float

Map Neg/Zero/Pos to -1./0./1. respectively. (There is no of_float here, but see Float.sign_exn.)

val flip : t ‑> t

Map Neg/Zero/Pos to Pos/Zero/Neg respectively.

val (*) : t ‑> t ‑> t

Neg * Neg = Pos, etc.

This provides to_string/of_string, sexp/bin_io conversion, Map, Hashtbl, etc.
