Subject: [OASIS Issue Tracker] Commented: (OFFICE-2470) 2.2 ExpressionCalculation is a mixure of observations, rules and possible suggestions
[ http://tools.oasis-open.org/issues/browse/OFFICE-2470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17696#action_17696 ] Dennis Hamilton commented on OFFICE-2470: ----------------------------------------- I've been scratching my head over the fact that not all evaluations down to values necessarily happen "bottom-up." Also, I simply can't square references and reference lists being data types. They are forms and they have semantics, but I don't think they are data types. That is especially true because a reference is to a cuboid of cells (default case, one cell) and a reference to multiple cells can also be expressed as a reference list that selects the same meaningful cells in one of many alternative ways. It is also exciting to see that some parameter lists can intermingle references and more-general expressions in an arbitrary way. There's something not working here. > 2.2 Expression Calculation is a mixure of observations, rules and possible suggestions > -------------------------------------------------------------------------------------- > > Key: OFFICE-2470 > URL: http://tools.oasis-open.org/issues/browse/OFFICE-2470 > Project: OASIS Open Document Format for Office Applications (OpenDocument) TC > Issue Type: Bug > Reporter: Patrick Durusau > Assignee: Patrick Durusau > Fix For: ODF 1.2 Part 2 CD 2 > > > 2.2 Expression Calculation is a mixture of observations, rules and possible suggestions. > For example, it starts by saying formulas are recalculated from "outside in," only to confess a few paragraphs later that is how it "appears to the end user." > There is one really glaring hole in my proposal, that also exists in the current language. > We describe the ordering of operators but as far as I can tell, we don't address the situation where there is a mixture of operators and functions. > Note that I changed #1 from constant number/string and added error. > As near as I can determine, the only possible outcomes of any expression are: > 1) a number > 2) a string > 3) an error > 4) a reference > So, application of these rules self-terminates when any of those conditions obtain. > Yes, that removes "constant number," "constant string" but those are defined elsewhere anyway. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
