Subject: [OASIS Issue Tracker] Commented: (OFFICE-2704) ACCRINT description is inconsistent
[ http://tools.oasis-open.org/issues/browse/OFFICE-2704?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=28625#action_28625 ] Andreas Guelzow commented on OFFICE-2704: ------------------------------------------ Note that ACCRINT = par * (rate/frequency) * sum {i=1 to NC} (A_i/NL_i) where A_i is "numberd of accrued days for the ith quasi-coupon period within odd period" NL_i is "normal length in days of the ith quasi-coupon period within odd period" and NC is "number of quasi-coupon periods that fit in odd period". is insufficient as a definition of this function since it is completely unclear how to obtain A_i, NL_i and NC. > ACCRINT description is inconsistent > ----------------------------------- > > Key: OFFICE-2704 > URL: http://tools.oasis-open.org/issues/browse/OFFICE-2704 > Project: OASIS Open Document Format for Office Applications (OpenDocument) TC > Issue Type: Bug > Components: OpenFormula > Affects Versions: ODF 1.2 CD 05 > Reporter: Andreas Guelzow > Assignee: Robert Weir > Fix For: ODF-Next > > > The description of ACCRINT has several issues: > 1) The constraint is given as: issue < first < settlement ; coupon > 0; par > 0. OOo and Excel clearly permit settlement<first and most examples on the web seem to be of that kind. > 2) The short description of calc_method reads "A logical value that specifies how to treat the case where settlement>first." which seems to imply that there is a permitted case where settlement > first does not hold. > 3) The formula given contains the undefined variables start-of-period and end-of-period. Especially in view of the statement "ACCRINT > supports short, standard, and long coupon periods.", it is not clear what those values are. > 4) If the constraint is changed, a formula for the settlement < first case is needed. -- 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
