val (=) : t -> t -> bool
val (>) : t -> t -> bool
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 ~compare: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

between t ~low ~high means low <= t <= high

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).

val succ : t -> t option

succ_exn t is the scalar value after t in the set of Unicode scalar values, and raises if t = max_value.

val succ_exn : t -> t
val pred : t -> t option

pred_exn t is the scalar value before t in the set of Unicode scalar values, and raises if t = min_value.

val pred_exn : t -> t
val is_char : t -> bool

is_char t is true iff n is in the latin-1 character set.

val to_char : t -> char option

to_char_exn t is t as a char if it is in the latin-1 character set, and raises otherwise.

val to_char_exn : t -> char
val of_char : char -> t

of_char c is c as a Unicode character.

val int_is_scalar : int -> bool

int_is_scalar n is true iff n is an Unicode scalar value (i.e., in the ranges 0x0000...0xD7FF or 0xE000...0x10FFFF).

val of_scalar : int -> t option

of_scalar_exn n is n as a Unicode character. Raises if not (int_is_scalar i).

val of_scalar_exn : int -> t
val to_scalar : t -> int

to_scalar t is t as an integer scalar value.
