Comment 11 for bug 1261048

Markus Mohrhard, thank you for your comment. While the prior work done in this area is appreciated, in that it replicates the output of Excel (yes, I already know LibreOffice isn't Excel), I think closing this as a Won't Fix is premature, especially predicated on a post from Wikipedia.

Despite this, venerable Gnumeric ( https://projects.gnome.org/gnumeric/ ) does in fact provide a more accurate result than LibreOffice or Excel in this instance:
lsb_release -rd
Description: Ubuntu Trusty Tahr (development branch)
Release: 14.04

apt-cache policy gnumeric
gnumeric:
  Installed: 1.12.9-1
  Candidate: 1.12.9-1
  Version table:
 *** 1.12.9-1 0
        500 http://us.archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages
        100 /var/lib/dpkg/status

I think this should be discussed much further technically before making such a judgement.

Thank you for your understanding.
