[OASIS Issue Tracker] (ODATA-784) Need to specify the behaviour of arithmetic operators on Decimal type

[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

    [ https://issues.oasis-open.org/browse/ODATA-784?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=59502#comment-59502 ] 

Ralf Handl commented on ODATA-784:
----------------------------------

Just noticed that Java BigDecimal defines the preferred scale of a BigDecimal operation identically for add, sub, mul, but subtracts the scale of the divisor from the scale of the dividend:

scaleof(A div B) = scaleof(A) - scaleof(B)
