Svante von Erichsen commented on OLINGO-1087:
---------------------------------------------
That would mean that OData v2 actually does not have a specification.
> Precision in EdmDecimal not calculated correctly
> ------------------------------------------------

> Key: OLINGO-1087
> URL: https://issues.apache.org/jira/browse/OLINGO-1087
> Project: Olingo
> Issue Type: Bug
> Components: odata2-core
> Affects Versions: V2 2.0.8
> Reporter: Svante von Erichsen
> Attachments: 0001-OLINGO-1087-Fix-calculation-of-precision.patch

> The "precision" found in a read number is currently at least the number of
> decimals (omitting trailing zeroes). That seems to be wrong, or at least not
> consistent with at least some server side view of the matter, for numbers
> smaller than 0.1 (the number shown has 35 decimals, but precision 34):
> org.apache.olingo.odata2.api.edm.EdmSimpleTypeException: The metadata
> constraints '[Precision=34]' do not match the literal
> '0.08102359900000000170194880411145277'.
