Inserting an whole number as a double results in a Int32 field of an entity

Which service(blob, file, queue, table) does this issue concern?

table

Which version of the Azurite was used?

3.16.0

Where do you get Azurite? (npm, DockerHub, NuGet, Visual Studio Code Extension)

npm

What’s the Node.js version?

16.3.1

What problem was encountered?

When using EntityProperty.GeneratePropertyForDouble((double?)1.0D) the data type of the property in the table is set to Int32, and not to Double, incorrectly.

When using EntityProperty.GeneratePropertyForDouble((double?)1.1D) the data type of the property in the table is set to Double, correctly.

Steps to reproduce the issue?

If possible, please provide the debug log using the -d parameter, replacing <pathtodebuglog> with an appropriate path for your OS, or review the instructions for docker containers:

-d "<pathtodebuglog>"

Please be sure to remove any PII or sensitive information before sharing!
The debug log will log raw request headers and bodies, so that we can replay these against Azurite using REST and create tests to validate resolution.

Have you found a mitigation/solution?

No

I shall look to make Azurite return the point in the double value, as the SDKs are using this to determine entity value type. That should resolve this issue.

Hi, Thanks for sharing the debug log. I tested this morning against the current main branch of Azurite on Windows 11 with nodejs version 14.15.4. I do not see this behavior in storage explorer. In your debug log I see that the request is for minimal metadata, using the Cosmos Table SDK: RequestHeaders:{"host":"127.0.0.1:10002","accept-charset":"UTF-8","maxdataserviceversion":"3.0;NetFx","accept":"application/json; odata=minimalmetadata","dataserviceversion":"3.0;","x-ms-client-request-id":"2cbbab00-06db-455d-8e9e-bd85866bfce8","user-agent":"Azure-Cosmos-Table/1.0.8 (.NET CLR 6.0.3; Win32NT 10.0.22000.0)"

which means that the data-type for the double value is not returned, and we return without the ‘.0’ suffix. {\"odata.metadata\":\"http://127.0.0.1:10002/devstoreaccount1/$metadata#TestTool/@Element\",\"odata.etag\":\"W/\\\"datetime'2022-03-18T07%3A47%3A59.9140000Z'\\\"\",\"PartitionKey\":\"GenericReadWriteTest\",\"RowKey\":\"a18e5cb5-d0f6-4e47-a1a8-7fb6ff5e4609\",\"TestDouble\":42,\"[e-mail]\":\"Edm.DateTime\",\"Timestamp\":\"2022-03-18T07:47:59.9140000Z\"}
