Eric Patterson updated OFFICE-3041:

    Component/s: OpenFormula

> Bit operations, still some ambiguity
> ------------------------------------
>                 Key: OFFICE-3041
>                 URL: http://tools.oasis-open.org/issues/browse/OFFICE-3041
>             Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
>          Issue Type: Bug
>          Components: Needs Discussion, OpenFormula
>    Affects Versions: ODF 1.2 CD 05
>            Reporter: Eric Patterson
>            Assignee: Eric Patterson
>             Fix For: ODF 1.2 CD 06
> As part of the fix in http://tools.oasis-open.org/issues/browse/OFFICE-2327, we've set the minimum to 48 bits, but in doing so, there is still ambiguity when doing shift operations.  If implementations have different maximums, you may get different results when shifting outside the range.  
> Assuming the minimum 48-bit support is provided, then BITLSHIFT(1,48) places the 1 in the 49th bit which is outside of the 48-bit range that's supported.  Is that bit lost (producing 0 as a result), or does that produce an error?
