BTW there will always be the chance of a small difference in the result of YEARFRAC(), because of leap years in case of Mode 1 (exact). The number of days in a year on which the result is based is the year of the first date. The result is the number of days between the two dates divided by the number of days in a year. So, even the number of days between two dates is identical, depending on whether the first date is a leap year, the result will differ a little bit.
This cannot be avoided, as a year has no fixed length with Mode 1 (exact). This unavoidable difference is not what causes this bug, this bug can be fixed :-) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to openoffice.org in Ubuntu. https://bugs.launchpad.net/bugs/127505 Title: [Upstream] [hardy] YEARFRAC function returns incorrect results for some dates Status in LibreOffice Productivity Suite: Confirmed Status in The OpenOffice.org Suite: In Progress Status in “libreoffice” package in Ubuntu: Triaged Status in “openoffice.org” package in Ubuntu: Won't Fix Bug description: Binary package hint: openoffice.org 1) lsb_release -rd Description: Ubuntu 11.04 Release: 11.04 2) apt-cache policy libreoffice-calc libreoffice-calc: Installed: 1:3.3.3-1ubuntu2 Candidate: 1:3.3.3-1ubuntu2 Version table: *** 1:3.3.3-1ubuntu2 0 100 /var/lib/dpkg/status 1:3.3.2-1ubuntu5 0 500 http://us.archive.ubuntu.com/ubuntu/ natty-updates/main i386 Packages 1:3.3.2-1ubuntu4 0 500 http://us.archive.ubuntu.com/ubuntu/ natty/main i386 Packages 3) What is expected to happen is when one types in a cell either: =YEARFRAC(DATE(1958,3,1),DATE(1996,1,1),1) =YEARFRAC(DATE(1958,3,1),DATE(1995,12,31),1) one gets two different results. 4) What happens instead is they are identical: 37.8356164384 37.8356164384 WORKAROUND: Use Gnumeric as the results are: 37.8364338364338 37.8357230348008 apt-cache policy gnumeric gnumeric: Installed: 1.10.13-1ubuntu1 Candidate: 1.10.13-1ubuntu1 Version table: *** 1.10.13-1ubuntu1 0 500 http://us.archive.ubuntu.com/ubuntu/ natty/universe i386 Packages 100 /var/lib/dpkg/status Original Reporter Comments: This occurs whenever the "End date" is in a leap year (New Year's Eve/Day is convenient) and the "Start date" is not in a leap year but is later than 28-Feb of its year. For example, "Start dates" between "1.1.1958" and "2.28.1958" in the above examples work correctly.
