New Proposal: 1) Because annotating numeric values of arrays is problematic, and we are no longer trying to use JSON Schema as our schema language, revert application of the numericValueException annotation and continue the 4.0 literal "INF", "-INF", and "NaN" values. 2) Support these values all numeric types. --> reduced to Decimal with floating scale by ODATA-1091 3) Support -INF and INF for Edm.Date and Edm.DateTimeOffset --> OData Temporal Extension Previously applied proposal from 2016-5-12: 1) Add a new annotation, "odata.numericValueException", with valid values "INF", "-INF" and "NaN". 2) Services don't return the property, just the property annotation specifying the value exception: "NumberOfODataUsers@odata.numericValueException":"INF" 3) Could be applied to any numeric type. 4) For 4.01 clients, always return this for all numeric types, including single/double, instead of as property values.
