Generating invalid `@js` (gen_js_api) expression

[joelburget]

I used this example (test.d.ts):

export interface CSSDataV1 {
    version: 1 | 1.1;
}

❯ ts2ocaml jsoo --preset=minimal --output-dir test-output test.d.ts
❯ ocamlfind gen_js_api/gen_js_api test-output/test.d.ts.mli
File "test-output/test.d.ts.mli", line 13, characters 50-64:
13 |   val get_version: t -> ([`L_n_1[@js 1] | `L_n_1_1[@js 1.100000]] [@js.enum]) [@@js.get "version"]
                                                       ^^^^^^^^^^^^^^
Error: Invalid expression

Changing 1.100000 to 2 works but floats all fail.

I'm not sure whether this is a ts2ocaml or gen_js_api bug. https://github.com/LexiFi/gen_js_api/blob/master/TYPES.md isn't clear what values are accepted in [@js] but only shows examples of ints and strings.

This is gen_js_api lacking a support for float enums. I will open a PR for it.

gen_js_api 1.0.9, which adds support for float enums, is now on OPAM. You should upgrade it and you don't have to use opam pin for gen_js_api anymore.
