Subject: [OASIS Issue Tracker] (ODATA-771) Exponential notation for Edm.Decimal values in JSON payloads
[ https://issues.oasis-open.org/browse/ODATA-771?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ralf Handl updated ODATA-771:
-----------------------------
Description:
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 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.
was:
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.
