Michael Bolz resolved OLINGO-229.
---------------------------------
Resolution: Not a Problem
Hi [~Michele EnergySys],
as far as I know the correct uri literal for an {{Edm.Double}} is {{200.5D}} or
{{200.5d}} so that you have to add a {{"D"}} at the end of your number. So it
is also defined in section {{2.2.2 Abstract Type System}} of [MS-OData
Specification|http://download.microsoft.com/download/9/5/E/95EF66AF-9026-4BB0-A41D-A4F81802D92C/\[MS-ODATA\].pdf]
(from [http://www.odata.org/documentation/odata-version-2-0/]).
But I have to admit that in your linked
[documentation|http://www.odata.org/documentation/odata-version-2-0/uri-conventions/]
no {{"D"}} is required.
Because current Olingo implementation is based on the linked document you have
to add the additional {{"D"}} and then the filter expression will work.
Kind regards,
Michael

> Project: Olingo
> Issue Type: Bug
> Components: odata2-core
> Affects Versions: V2 1.2.0
> Reporter: M Carissimi
> Assignee: Michael Bolz
>
> Hello, I have an OData service which uses custom built Processor and
> Provider. Some of my Entities contain properties of type Edm.Double. When I
> use the binary operators (eq, gt, lt, ge, le) with these attributes they only
> work if I compare the value to an integer number.
> The following filter query works:
> $filter=WATER gt 200
> where as the following query fails:
> $filter=WATER gt 200.5
> According to the OData 2.0 documentation (section 4.5 of
> http://www.odata.org/documentation/odata-version-2-0/uri-conventions/) it
> should be possible to compare a value with a double number. Can you please
> clarify?
