val 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

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

val 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.

val insert_delimiter : string -> delimiter:char -> string

insert_delimiter_every ~chars_per_delimiter:3

val insert_underscores : string -> string
