UnmarshalBSON and MarshalBSON serialization

[1140251]

when saving to mongodb with mongo go driver, the decimal.Big is created with an empty context only.
Maybe you don't want this dependency, but how can serialize this?

As a workaround I'm saving as Float64 and converting to decimal.Big when performing operations, but is not the most eloquent way for me.

Could you elaborate a little bit more?

I think he means that when saving a decimal.Big in mongodb this is the result that is written into the db.

I'm too wondering if it would make if this library would support marshaling into (I guess) a Decimal128 as supported by mongodb.
