Subject: [OASIS Issue Tracker] Updated: (ODATA-256) Simplify numeric data types
[ http://tools.oasis-open.org/issues/browse/ODATA-256?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ralf Handl updated ODATA-256: ----------------------------- Proposal: Define an abstract type Edm.Number as a specialization of Edm.PrimitiveType and a generalization of all numeric primitive types that can be used in term definitions and in complex types used within term definitions. (was: Define a single Numeric data type with facets to specify its range and precision, e.g. - MinValue - MaxValue - ItFloats - ... Have a close look at XML Schema 1.1 and IEEE 754 to detect the required facets.) Environment: [Proposed] Description: Computer history has provided us with a growing number of numeric data types, and quite a few of them are reflected in Edm primitive types. Integer types: - Byte (0..2^8) - SByte - Int16 - Int32 - Int64 - Decimal Scale=0 Fixed-point types - Decimal with VariableScale="false", see ODATA-76 Floating-point types - Decimal with VariableScale="true", see ODATA-76 - Single - Double Especially for defining vocabularies it would be helpful to have an abstract type Edm.Number that can be applied to any of the numeric primitive types. was: Computer history has provided us with a growing number of numeric data types, and quite a few of them are reflected in Edm primitive types.
