      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.

          Field Original Value New Value
          Proposal 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.           		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.
