Subject: [OASIS Issue Tracker] Commented: (OFFICE-3771) Public Comment: 2's complement negative and 10 binary digits

    [ http://tools.oasis-open.org/issues/browse/OFFICE-3771?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=31422#action_31422 ] 

Robert Weir  commented on OFFICE-3771:

I could see the two's-complement conversion being useful for some comp sci or engineering students.  Yes, it is specialized.  But so is dec2bin and similar.  Not many outside of these fields deal with binary or hexadecimal.  But where to draw the line?  Could just as well as for a float2bin function to return IEEE representation of an input float.

> this just to be sure the RFEs for ODv1.3 was tracked and so can be discussed 
> and maybe added.
> The RFEs are:
> 1) a modification to BASE(), to support two's complement negative binary 
> numbers.
> Use the optional 3th parameter: 'Integer MinimumLength' to specify the bit 
> size of the machine word for negative numbers.
