module T : sig ... end

Signature

include Base.Comparable_intf.S with type t := T.t
include Base.Comparable_intf.Polymorphic_compare with type t := T.t
include Base.Comparisons.Infix with type t := T.t
val (>=) : T.t -> T.t -> bool
val (<=) : T.t -> T.t -> bool
val (=) : T.t -> T.t -> bool
val (>) : T.t -> T.t -> bool
val (<) : T.t -> T.t -> bool
val (<>) : T.t -> T.t -> bool
val equal : T.t -> T.t -> bool
val compare : T.t -> 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.t -> T.t
val max : T.t -> T.t -> T.t
val ascending : T.t -> 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 -> T.t -> int
val between : T.t -> low:T.t -> high:T.t -> bool
val clamp_exn : T.t -> min:T.t -> max:T.t -> 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).

val clamp : T.t -> min:T.t -> max:T.t -> T.t Base.Or_error.t

val validate_ubound : max:T.t Base.Maybe_bound.t -> T.t Base.Validate.check
