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.
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)
.

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

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

val of_scalar : int ‑> t option
of_scalar_exn n
is n
as a Unicode character. Raises if not (int_is_scalar
