Sourceval int_to_int32 : int -> int32 option

Ocaml has the following integer types, with the following bit widths on 32-bit and 64-bit architectures.

                        arch  arch
            type        32b   64b
            ----------------------
            int          31    63  (32 when compiled to JavaScript)
            nativeint    32    64
            int32        32    32
            int64        64    64

In both cases, the following inequalities hold:

  width(int) < width(nativeint)
  && width(int32) <= width(nativeint) <= width(int64)

The conversion functions come in one of two flavors.

If width(foo) <= width(bar) on both 32-bit and 64-bit architectures, then we have

 val foo_to_bar : foo -> bar

otherwise we have

  val foo_to_bar     : foo -> bar option
  val foo_to_bar_exn : foo -> bar

Sourcemodule Make (I : sig ... end) : sig ... end

human-friendly string (and possibly sexp) conversions

Sourcemodule Make_hex (I : sig ... end) : sig ... end

in the output, to_string, of_string, sexp_of_t, and t_of_sexp convert between t and signed hexadecimal with an optional "0x" or "0X" prefix.

Sourcemodule Make_binary (I : sig ... end) : sig ... end

in the output, to_string, to_string_hum, and sexp_of_t convert t to an unsigned binary representation with an "0b" prefix.

Sourceval sexp_of_int_style : [ `No_underscores | `Underscores ] ref

global ref affecting whether the sexp_of_t returned by Make is consistent with the to_string input or the to_string_hum output

Sourceval insert_delimiter_every : string -> delimiter:char -> chars_per_delimiter:int -> string

utility for defining to_string_hum on numeric types -- takes a string matching (-|+)?0-9a-fA-F+ and puts delimiter every chars_per_delimiter characters starting from the right.

Sourceval insert_delimiter : string -> delimiter:char -> string

insert_delimiter_every ~chars_per_delimiter:3

Sourceval insert_underscores : string -> string

insert_delimiter ~delimiter:'_'
