Subject: [OASIS Issue Tracker] Created: (ODATA-557) Allow exponential notation for Edm.Decimal
Allow exponential notation for Edm.Decimal
------------------------------------------
Key: ODATA-557
URL: http://tools.oasis-open.org/issues/browse/ODATA-557
Project: OASIS Open Data Protocol (OData) TC
Issue Type: Improvement
Components: OData ABNF Construction Rules, OData ATOM Format , OData CSDL, OData JSON Format, OData Protocol , OData URL Conventions
Affects Versions: V4.0_CSD03
Environment: [Proposed]
Reporter: Ralf Handl
Fix For: V4.1_WD01
IEEE754 also defines the DECFLOAT data type for high-precision decimal arithmetic. They have 16 or 34 decimal digit mantissas and exponents between -383 and +384 or -6143 and +6144.
Representing them exactly in current Edm.Decimal would result in at most 34 non-zero digits and several thousand zeroes. This waste can easily be avoided by allowing exponential notation also for Edm.Decimal.
