Bastiaan J. Braams, thank you for performing the apport-collect. In the
future, please do not use dropbox, but instead just add the attachment
to the Launchpad report.

Despite this, converting your .ods to xls and opening Excel, I see the
exact same results. So, from a Excel compatibility expectation
perspective, which is important to many unless a clear cut benefit
exists that significantly outweight the negatives, the results are
expected as encountered.

Despite this, in order to create a more streamlined report, please feel
free to focus the discussion down to one particular row of cells and
function, not all cells and all functions encountered, what was
expected, and what specific value you obtained, and why this would
benefit LibreOffice (including those in the expectation compatibility
camp).

Title:
  Wrong results from rounding functions for large argument

Status in “libreoffice” package in Ubuntu:
  Incomplete

Bug description:
  I am using Ubuntu 12.04.3 LTS and within that LibreOffice 3.5.7.2,
  Build ID: 350m1(Build:2). This report concerns LibreOffice Calc;
  functions roundup, rounddown, trunc, ceiling, floor, int, even and
  odd.

  Let y=power(2,50)+1 and please note that all integers up to
  power(2,53) are exactly representable. Therefore I expect that
  rounding y to integer will return y exactly, for any of the functions
  roundup, rounddown, trunc, ceiling, floor and int. I also expect that
  even(y)=y+1 and odd(y)=y.

  Actual results: functions roundup(y,0), rounddown(y,0), trunc(y,0),
  ceiling(y,1), floor(y,1) and int(y) all return y+5. Moreover,
  even(y)=y and odd(y)=y+6 according to Calc.

  (Note that the second argument to roundup, rounddown and trunc
  indicates number of places behind the decimal symbol and the second
  argument to ceiling and floor indicates the unit.)

  There are similar problems with these rounding functions when rounding
  to some number (>0) of places behind the decimal symbol.
