      If no argument speaks for keeping Edm.Decimal, the proposal is to align both features by assigning Edm.Int64 also to the virutal property $count.

      Description

      In the Data Aggregation extension, the virtual property $count has type Edm.Decimal (http://docs.oasis-open.org/odata/odata-data-aggregation-ext/v4.0/cs02/odata-data-aggregation-ext-v4.0-cs02.html#_Toc435016573). In contrast the JSON Format specification states that the result of the system query option has type Edm.Int64 (http://docs.oasis-open.org/odata/odata-json-format/v4.0/os/odata-json-format-v4.0-os.html#_Toc372793054).

      Since aggregation rather reduces the number of entities in a result collection, question is whether there is some unmentioned reason for this discrepancy.
