Subject: Re: [office-comment] [office-formula] predraft 8 of 2007-12-28,section 6.9.6, function days360 comment
Not wishing to divert from the current subject line (and/but since we are on the topic of[office-comment] [office-formula]... I thought that it might be appropriate at this time to draw attention a particular question that was raised some time ago with regards to the absence of an Economic Rate of Return (ERR) Functionality within Lotus 1-2-3, OpenOffice Calc... Thus, as a point of reference here is an extract from a 1998 Lotus Development Corporation communication; "Re: Concerning the issues with 1-2-3 that are talked about in the documentation you gave me, most of the issues are related to converting files between older and newer versions of product and converting documents between Lotus and Microsoft. Anytime a file is saved backwards or saved with an older file format than the format the file was created under, such as saving a 1-2-3 , 97 file for Windows 95 into a WK1 format for DOS, then naturally we are expected to loose certain features due to technology and features that are present now that were not present 8 - 10 years ago. Similarly, if we try to convert a file from Lotus into Excel or Excel into Lotus, due to differences in the products not every feature will be converted perfectly with the file filters that are available. Both Lotus and Microsoft create similar spreadsheet programs; however, there are several differences in both programs and these differences will remain to distinguish the products apart. We do try to design conversion filters that will allow as much of the file formats as possible to be exchanged and converted without disrupting the actual file design and format. In one of your letters you made mention of the @IRR and @ERR functions in the 1-2-3 product. By design the @IRR (notably "absent" in Open Office) will calculate the Internal Rate of Return; where the @ERR is used in conjunction with other formulas, posted was an "ERR" showing an error was received in the calculations. As far as I can see in the program I cannot find an @ERR function that will allow us to calculate an Economic Rate of Return" From the above, is anyone in a position to say if any of the current Spread Sheets (Lotus 1-2-3, Excel, Open Office Calc...) that are available on the market can successfully convert from Internal Rate of Return (IRR) to Economic Rate Of Return (ERR) values; also, whether or not there are ongoing activities to have the Economic Rate of Return functionality integrated into Lotus 1-2-3, Open Office Calc et cetera et cetera and whether this Functionality has been agreed by the International Organisation for Standardisation (ISO) Thanks you.
