support decimal and fraction about typedload HOT 4 OPEN

OK, I've made a few tries and made it all work as you have described and as expected according to the documentation for Python's decimal module. I wish generating decimals from floats had a nicer syntax in Python without having to use strings or rounding, but I can see why things are the way they are. Thanks!

This would be very nice. I'm in the process of redesigning the https://github.com/cinemagoer/cinemagoer (former imdbpy) code base (in https://github.com/cinemagoer/cinemagoerng) and I'm using typedload for deserialization. Great library, thank you very much! Anyway, movie ratings are given as floats but I believe decimal would be the proper type for that.

It's really really easy to do, but I haven't done it because it would mean importing them automatically even when they aren't used (most of the times, I guess).

Unless I think of a way of doing a conditional import, I don't think it's a good idea to just blindly import the module.

I think float is fine, I don't think you will need excessive precision for ratings.

Anyway you can pass strconstructed={decimal.Decimal} to support it.

This will override the default strconstructed set, so if you want to use also the types that are in there by default you must create the loader/dumper object and do like l.strconstructed.add(decimal.Decimal).

Unfortunately non-integer numbers and computers don't get so well together. I still think for your case you don't need that much precision and a float would be fine.
