[Desktop-packages] [Bug 1261048] Re: Wrong results from rounding functions for large argument
Thank you Christopher M. Penalver for the guidance towards a more streamlined problem report. Row 5 in the posted spreadsheet, LibreOfficeRoundingIssues.ods, shows the precise errors described in my initial report here. The cells in that row contain, successively, x=50, y=power(2,x)+1, round(y,0)-y, roundup(y,0)-y, rounddown(y,0)-y, trunc(y,0)-y, ceiling(y,1)-y, floor(y,1)-1, int(y)-y, even(y)-y and odd(y)-y. The expected result is a 0 in the cells for functions round ... int, a 1 for even(y)-y (because y is odd), and a 0 for odd(y)-y. As is highlighted in yellow in the sheet the actual result is different in each case except for the first function, plain round. A minimal set of instructions to reproduce the core of the problem follows. Open a new blank spreadsheet. In the A1 cell enter =power(2,50)+1 (without the quotes) and in the B1 cell enter =rounddown(a1,0)-a1 (without the quotes). Expected result: B1=0. Actual result: B1=5. I take it as understood that when an integer is rounded to integer then the result should be the same integer. The actual result in LibreOffice is a different integer, therefore it is a wrong result. I am asked to explain the significance of the error and to address possible negatives in fixing it. To be clear, the relative magnitude of the error is tiny and when viewed purely as a numerical error it is insignificant in any engineering or financial context. The risk of this kind of error in applied code is rather that it breaks assumptions. A person may write a spreadsheet program and take for granted that for positive argument y, rounddown(y,0) can never exceed y. The present report shows that this entirely justifiable assumption is broken in LibreOffice Calc. That risk is a risk to a third party (user of LibreOffice) and not directly to the LO project team. The significance of this error directly to LibreOffice is, I think, primarily a risk to the reputation of the product. There may be cases where one wants to follow Excel in a questionable specification of a spreadsheets function, because users rely on that specification. However, I cannot conceive of any spreadsheet design that would in any way rely on erroneous behavior of the rounding functions for large argument. Therefore I think that the Calc team could correct this error without concern over breaking any compatibility with Excel. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1261048 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).

[Desktop-packages] [Bug 891812]
The presumed cause of the bug is that the multinomial is computed as a ratio of factorials; this would indeed cause an overflow when the sum of the arguments exceeds 170. Please note that for the implementation of the Binomial in LibreOffice Calc (function COMBIN) no such restriction applies; it is computed carefully to avoid unnecessary overflow. Please note also that the bug with multinomial would be almost trivial to fix. A recurrence for computing the multinomial function as a product of binomials may be found in the description of the multinomial function in the Sage mathematics system: http://www.sagemath.org/doc/reference/sage/rings/arith.html#sage.rings.arith.multinomial The associated 5-line Python code by Gabriel Ebner may be found here: http://trac.sagemath.org/sage_trac/attachment/ticket/3132/trac3132-2.diff I believe that this is a very natural way to compute the multinomial, and it would completely remove the problem of unnecessary overflow. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/891812 Title: [Upstream] Calc: MULTINOMIAL only supports parameters up to 170 Status in LibreOffice Productivity Suite: Confirmed Status in “libreoffice” package in Ubuntu: Triaged Bug description: 1) Lucid: lsb_release -rd Description: Ubuntu 10.04.3 LTS Release: 10.04 Oneiric: lsb_release -rd Description: Ubuntu 11.10 Release: 11.10 2) Lucid: apt-cache policy libreoffice-calc libreoffice-calc: Installed: 1:3.3.2-1ubuntu2~lucid1 Candidate: 1:3.3.2-1ubuntu2~lucid1 Version table: *** 1:3.3.2-1ubuntu2~lucid1 0 500 http://ppa.launchpad.net/libreoffice/ppa/ubuntu/ lucid/main Packages 100 /var/lib/dpkg/status Oneiric: apt-cache policy libreoffice-calc libreoffice-calc: Installed: 1:3.4.4-0ubuntu1~ppa1 Candidate: 1:3.4.4-0ubuntu1~ppa1 Version table: *** 1:3.4.4-0ubuntu1~ppa1 0 500 http://ppa.launchpad.net/libreoffice/ppa/ubuntu/ oneiric/main i386 Packages 100 /var/lib/dpkg/status 1:3.4.3-3ubuntu2 0 500 http://us.archive.ubuntu.com/ubuntu/ oneiric/main i386 Packages LibreOffice Calc 3.4.3, OOO340m1 (Build:302) 3) What is expected to happen in a blank LibreOffice Calc document is when one types in a cell: =MULTINOMIAL(1000,0) it returns 1. 4) What happens instead is it returns Err:502.

[Desktop-packages] [Bug 891812] Re: [Upstream] Calc: MULTINOMIAL only supports parameters up to 170
Feel free to implement it. I appreciate the suggestion and the pointer to the code. I can see how the computation is done; a ratio of factorials indeed. However, there is a lot of code surrounding the core numerical computation that is quite mysterious to me. So, with due respect for the creators and developers of LibreOffice Calc I have to decline to touch the code myself. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/891812 Title: [Upstream] Calc: MULTINOMIAL only supports parameters up to 170 Status in LibreOffice Productivity Suite: Confirmed Status in “libreoffice” package in Ubuntu: Triaged Bug description: 1) Lucid: lsb_release -rd Description: Ubuntu 10.04.3 LTS Release: 10.04 Oneiric: lsb_release -rd Description: Ubuntu 11.10 Release: 11.10 2) Lucid: apt-cache policy libreoffice-calc libreoffice-calc: Installed: 1:3.3.2-1ubuntu2~lucid1 Candidate: 1:3.3.2-1ubuntu2~lucid1 Version table: *** 1:3.3.2-1ubuntu2~lucid1 0 500 http://ppa.launchpad.net/libreoffice/ppa/ubuntu/ lucid/main Packages 100 /var/lib/dpkg/status Oneiric: apt-cache policy libreoffice-calc libreoffice-calc: Installed: 1:3.4.4-0ubuntu1~ppa1 Candidate: 1:3.4.4-0ubuntu1~ppa1 Version table: *** 1:3.4.4-0ubuntu1~ppa1 0 500 http://ppa.launchpad.net/libreoffice/ppa/ubuntu/ oneiric/main i386 Packages 100 /var/lib/dpkg/status 1:3.4.3-3ubuntu2 0 500 http://us.archive.ubuntu.com/ubuntu/ oneiric/main i386 Packages LibreOffice Calc 3.4.3, OOO340m1 (Build:302) 3) What is expected to happen in a blank LibreOffice Calc document is when one types in a cell: =MULTINOMIAL(1000,0) it returns 1. 4) What happens instead is it returns Err:502.

[Desktop-packages] [Bug 891812] [NEW] calc: numerical error in the multinomial function
Public bug reported: The multinomial function is defined as a ratio of factorial functions, but that is not how it should be computed; it would cause unnecessary overflow. However, the following expression causes a numerical error (#502): =MULTINOMIAL(1000,0) The correct mathematical value is just 1 and that was the expected result. Note that, for example, multinomial(100,0) is computed correctly; the value is 1. In general the multinomial may be computed as a product of binomials, by recursion on the number of variables. I'm using Ubuntu 11.10 and LibreOffice Calc 3.4.3, OOO340m1 (Build:302). ** Affects: libreoffice (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/891812 Title: calc: numerical error in the multinomial function Status in “libreoffice” package in Ubuntu: New Bug description: The multinomial function is defined as a ratio of factorial functions, but that is not how it should be computed; it would cause unnecessary overflow.
