Subject: [OASIS Issue Tracker] (ODATA-784) Need to specify the behaviour of arithmetic operators on Decimal type
[ https://issues.oasis-open.org/browse/ODATA-784?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Evan Ireland updated ODATA-784: ------------------------------- Proposal: If A and B are values of type decimal, with scales scaleof(A) and scaleof(B), then: scaleof(A add B) = max(scaleof(A), scaleof(B)) scaleof(A sub B) = max(scaleof(A), scaleof(B)) scaleof(A mul B) = scaleof(A) + scaleof(B) scaleof(A div B) = scaleof(A) For decimal values with "floating" scale, additional consideration (or separate rules?) may be required. was: If A and B are values of type decimal, with scales scaleof(A) and scaleof(B), then: scaleof(A add B) = max(scaleof(A), scaleof(B)) scaleof(A sub B) = max(scaleof(A), scaleof(B)) scaleof(A mul B) = scaleof(A) + scaleof(B) scaleof(A div B) = scaleof(A) For decimal values with floating scale, additional consideration (or separate rules?) may be required. > Need to specify the behaviour of arithmetic operators on Decimal type > --------------------------------------------------------------------- > > Key: ODATA-784 > URL: https://issues.oasis-open.org/browse/ODATA-784 > Project: OASIS Open Data Protocol (OData) TC > Issue Type: Improvement > Components: OData URL Conventions > Affects Versions: V4.0_OS > Environment: Proposed > Reporter: Evan Ireland > Priority: Minor > Fix For: V4.01_WD01, V4.0_ERRATA03 > > > The rules for scale of results of decimal arithmetic operators are not specified. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
