Subject [jira] [Commented] (OLINGO-1087) Precision in EdmDecimal not calculated correctly
Date Thu, 02 Mar 2017 11:25:45 GMT

    [ https://issues.apache.org/jira/browse/OLINGO-1087?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15892094#comment-15892094

Svante von Erichsen commented on OLINGO-1087:
---------------------------------------------

That would mean that OData v2 actually does not have a specification.

> 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'.
