DocumentClient query with Int64 where clause is incorrect when converted and sent to Azure

Question

The code below constructs a query with a lambda expression involving an Int64. When the query is converted and sent to Azure, it is incorrect. I captured the request to Azure using Fiddler for the example below, and the body contained:
{"query":"SELECT * FROM root WHERE (root.car.id = 1.01036229983142E+16) "}
Notice the constant does not match that of the code. Is this a bug in Azure DocumentDB library? If so, where can I submit a bug?
long carId = 10103622998314238;
IQueryable<MyDocument> query = documentClient.CreateDocumentQuery<MyDocument>("<collectionLinkGoesHere>", new FeedOptions { MaxItemCount = 1 });
query = query.Where((MyDocument d) => d.Car.Id == carId);
await query.AsDocumentQuery().ExecuteNextAsync<T>();

@kurifodo1, DocumentDB follows the JSON standard for numbers, which is http://en.wikipedia.org/wiki/IEEE_754 notation. So any long integer gets serialized to a double stored as IEE754, and will lose some precision. While this isn't the most intuitive behavior,
it's important in order to be compliant with other tools and platforms that speak JSON.
If you'd like to just perform equality queries, consider storing this as a string. If you'd like to perform range queries, consider breaking up the number into two parts (high and low), similar to the BigInteger structure in C#.
Hope this helps.
