Subject: [OASIS Issue Tracker] Commented: (OFFICE-2327) Bit OperationFunctions Inadequately Defined

    [ http://tools.oasis-open.org/issues/browse/OFFICE-2327?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17903#action_17903 ] 

Eric Patterson commented on OFFICE-2327:

Does it truncate arithmetic by 48 bits in result? What is result of shifting left 1 by 49, is it zero or  should it be shifted by 1?  What about operations over negative numbers? What we do with sign bits?

>                 URL: http://tools.oasis-open.org/issues/browse/OFFICE-2327
>             Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
>          Issue Type: Bug
>          Components: OpenFormula
>    Affects Versions: ODF 1.2 Part 2 CD 1
>         Environment: This issue applies to OpenFormula drafts through OpenDocument-part2-draft17-editor-revision.odt
>            Reporter: Dennis Hamilton
>            Assignee: Dennis Hamilton
>             Fix For: ODF 1.2 Part 2 CD 2
> [This topic has been discussed on the list and perhaps on calls.  This issue and its sub-issues bring management of the various issues to JIRA.]
> The Bit Operations Functions do not precisely establish the sequence of bits that correspond to a given Integer parameter value and the Integer result.  Although this is conventional it needs to be described precisely so that the effect of "left" and "right" shifting is understood, including the loss of bits to the left and right, and the introduction of 0 bits on the right and left.
> The means by which the number of bits is specified/known needs to be addressed both with respect to what an OpenFormula-hosting specification might constrain and how implementtion-defined support might be specified, including absence of support for the set of Bit Operation functions..
