Michael Pizzo commented on ODATA-771:
-------------------------------------
As per 2015-2-5 meeting:
Inclination is to make this clarification for JSON payloads, and to add a suggestion to service implementers in URL Conventions and ABNF that they should support this in URLs, but we want to verify behavior of existing implementations.
> Exponential notation for Edm.Decimal values in JSON payloads

> Key: ODATA-771
> URL: https://issues.oasis-open.org/browse/ODATA-771
> Project: OASIS Open Data Protocol (OData) TC
> Issue Type: Improvement
> Components: OData JSON Format
> Affects Versions: V4.0_ERRATA02
> Environment: [Proposed]
> Reporter: Ralf Handl
> Fix For: V4.0_ERRATA03
>
>
> IEEE754 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.
> The correct, lossless representation of DECFLOAT values is an Edm.Decimal with unspecified precision and variable scale.
> The OData JSON Format represents Edm.Decimal values as JSON numbers, and JSON numbers allow exponential notation, so
> "VeryLittle":1.4e-6143
> should be valid in JSON payloads.
