Double / Long deserialize

[yuvalp-k2view]

Sometimes it is useful to parse '5' as long vs '5.0' as double, especially when parsing arbitrary data.

This would make the serialize/deserialize of numbers symetric (5.0 > "5.0" > 5.0, 5L > "5" > 5L)

I'd like to suggest a new builder param:
setNumberDererializationPolicy()
default will remain as is
however, user will be able to specify:
setNumberDererializationPolicy(NumberDererializationPolicy.LONG_SUPPORT)

I think this presents a good compromise between the spec being strictly double and the reality where double has precision issues and users need a way to store longs in arbitrary json.

We'd be happy to create a PR if this is acceptable

Possible duplicate of #1290 :

Gson gson = new GsonBuilder()
  .setNumberToNumberStrategy(ToNumberPolicy.LONG_OR_DOUBLE)
  .create();

I agree... but I see this PR is waiting for a long time. Do you know if there is anything wrong with it? If there are fixes needed we'd be happy to contribute.

Do you know if there is anything wrong with it?

No idea, there was no review from the project members.
