Numbers gives wrong answer.

On my numbers (v3.1) spreadsheet on Mac (Mavericks, iMac , OSX 10.9.1), 83177.2-78342.53 comes out 4834.66999999999.  I'm pretty sure this is the wrong answer (there should be no repeating digit at the end.  What gives?

John,
this is a fact of compuing that there finite precision available.  People write very sophisticated and expensive libraries for extrememly large and small numbers.  At 11 decimal places you are past the believable, and reaonable, number of digits of precision.
the error of 4834.66999999999 vs 4834.67 is:
|4834.66999999999 - 4834.67| / 4834.67
this is: 2.068e-13 percent
I would suggest using the number of decimal places that are reasonable for your data and get something done rather than focusing on this detail.  It is not a problem and, while I am not an Apple employee, based on my experince as an embedded developer, and Electrical Engineer, and based on my experience with Apple you can expect no change with regard to this.
If you are very interested in precision and range of digital values peruse this information:

  • Why java gives wrong answer

    give wrong answers for large calculations)Use BigDecimal with MathContext or roll your own Fraction class- this way any repeating decimal is represented exactly.

  • Multisim ac analysis for simple resonant circuit gives wrong answer

    Hello,
    I tried to run a simulation of the attached simple tank circuit and the multisim results are wrong (don't match hand calculations or microcap simulation results). I tried experimenting with simulation settings with no effect. Can you help me resolve?

    Hi Steve,
    Run attached circuit, I was able to similar results as Microcap.  This screen shot shows the AC setup I used just in case you are not running Multisim 13.

  • Calculator gives wrong answer

    Imac 2,7 GHz Core i5. Mavericks updated. Calculator 10.8. I enter 10+10/2 and get 15. I enter 10+10= and get 20. I then divide result by two and get correct answer-10. But. Calculator broke the result (20) into 10+10 then divided by 2. (See entry 3 in Paper Tape). Simple 20 divided by 2 computes the correct answer-10. See Screen Capture. Any thoughts.

  • CALCULATE_TAX_ITEM gives wrong values for Scess and HScess in PO Print

    Dear Friends,
    I am working with PO Print in smartforms hare the Fm CALCULATE_TAX_ITEM is gives wrong values for Scess and HEcess if I put the Gate pass (Basic Excise Duty) Manually.
    And one more Issue is as if I check any line item condition taxes than imediatly when I see the print the all line items Scee and HEcess displays same which I have saw.
    If there is a single line item in PO than there is no issue any way.
    kindly suggest to resolve the issue.
    Regards,
    D Tarun Kumar

    Hi,
    I had the same issue, that taxes on invoice tab of PO was not printed correctly on PO form by calling CALCULATE_TAX_ITEM.
    If you want to have the same tax value as komp-mwsbp, that use following form routine call before FB CALCULATE_TAX_ITEM.
    perform j_1b_save_tax_fields(saplmepo) using ekko ekpo lfa1.
    This is used in transaction me23n also.
    Kind regards,

  • Reviewing Slides On Wrong Answer?

    When in questions is there a way of reviewing previous slides when a wrong answer is given; for example:
    A standard presentation of 50 slides is viewed and then candidates are taken to the question slides
    If question 1 is answered correctly it moves onto question 2
    if question 2 is answered incorrectly the candidate is then taken taken to the relevant slide (say slide 30) and returned to question 2 for another attempt.
    The only way I have managed to do this so far is to do a slight workaround by changing the way the reporting works i.e. duplicating the relevant reiew slides and putting them after the question slides.  Unfortunately this means the only way I can record their scores is to show quiz attempt not the native scoring results because on each review (out of the quiz) it resets the scores and shows an overall quiz fail for each wrong answer.  This obviously isn't the correct way of reporting quiz scores i.e.
    Number of questions set
    Incorrect answers
    Correct answers
    Percentage
    Pass/Fail
    This means that using this workaround I'm not getting the level of reporting normally available
    So my question is simply, is there a proper way I can record the correct scores and still retain the ability to review wrong answers?  This approach encourages a pro-active way to learn instead of penalising people for incorrect answers and allows them to learn without having to sit through a long presentation more than once - hence me wanting keep this style and be able to get full featured reporting.
    I apologise if I'm being a little long-winded in my explanation or indeed if I'm missing something pretty basic with the software.
    Many thanks in advance for anyone that may be able to help me with this
    Kind regards
    Martyn

    Hello Martyn
    Do not know if this has anything to do with etiquette, just did not know if you were asking me or the other user more help.
    As we both explained: with the Question slides that are in CP (will call them the default Quiz slides) this will not be that easy. You will have to give a lot of attempts for the Quiz to the user to make this possible. There is no way to change the system variables that store the score (such as cpQuizInfoTotalProjectPoints). If you want to realize your workflow you need to construct the Question slides yourself. That is why I offered some articles I published about this subject in CP5.
    You are not the first to ask for this kind of workflow, plan to work out an example but that will not be done today because of other priorities (some exams to be graded are waiting for me). The idea in steps is:
    Create your question slides using non-interactive objects like text captions, images and interactive ones buttons, text entry or click boxes (that get a score); this will not be possible for all kind of Question types, dragging p.e. as for matching or sequence questions is not possible, hotspot is possible.
    Be sure that all slides (to be reviewed before giving a second answer after an incorrect answer) are in the quizzing range (between first scored 'thing' and the score slide)
    On incorrect answer, create an advanced action that jumps to the slide(s) to be reviewed; on finishing those slides have an action that returns them to the question slide.
    On re-entering the question slide, re-initialize the score (to 0 if there is no 'penalty' because of the review) so that the user can answer again.
    Is this the workflow that you want? Which kind of question slides are you using? Is there a 'penalty' if the review possibility is used, I mean is the score that can be obtained lower than the first one?

  • Setting the time automatically, or manually yet still gives wrong time.

    Ever since I've updated my 5c, the time keeps messing around. It's never the right time. I've tried manual and also set it automatically. It keeps delaying in time and gives wrong hour/minutes. I cannot set the alarm or do anything because the time is just wrong. I don't have a problem with my other apple devices regarding the new software update, it's just with this phone.

    Hello Basilsami,
    It sounds like your phone is not keeping the correct time and date, either when set to automatic, or manual. I recommend these troubleshooting steps from the article named:
    iOS: Troubleshooting issues with date and time
    http://support.apple.com/kb/ts3920
    Follow these steps. Test after each step to see if the issue is resolved.
    Ensure that the version of iOS on your device is up to date.
    If the option to enable date and time automatically is available, turn it on. Tap Settings > General > Date & Time.
    Ensure that your time zone is set up correctly. Tap Settings > General > Date & Time > Time Zone.
    If the incorrect date, time, or time zone is being set up automatically on the device, please notify your cellular provider. In the meantime, tap General > Date & Time and turn off Set Automatically. Then set the appropriate time and time zone manually.
    Note: The option to set automatically might not be available on all carriers in all countries.
    Additional Information
    Note: If you find that your device's time is incorrect after you sync with your computer, your computer's time may be incorrect. Verify the computer's time in System Preferences > Date & Time (you may want to select the checkbox to set the computer's date and time automatically).
    Thank you for using Apple Support Communities.
    All the very best,
    Sterling

    The addition button is working, but i cant seem to make minus and multiply button work, they get wrong answer when i use them.. what could bee the problem with my code

    Sorry, but I don't see a simple fix in this code here (Hopefully I'm wrong and someone else will see this, but I don't) Because of this, I recommend that you fully scrap this code and start over from square one. I don't think that you really "see" your logic here. To help you see what you are trying to do, you need to separate your logic from your GUI. Try to build a non-gui calculator that works via simple console menu. Once you get this working, then use this code to create a GUI calculator.

    This is a bug. Got to be a bug.
    This should be nothing to do with indeterminate results from ROWNUM, and nothing to do with read consistency at the point of statement start time in session2., surely.
    Session 2 should never return 100101 once the lock from session 1 is released.
    The SELECT FOR UPDATE should restart and 100101 should not be selected as it does not meet the criteria of the select.
    A statement restart should ensure this.
    A number of demos highlight this.
    Firstly, recall the original observation in the original test case.

    Let's reset the data and drop the index:
    Session1>UPDATE taxids SET status=0 where taxid=100101;
    1 row updated.
    Session1>commit;
    Commit complete.
    Session1>drop index NI_TaxIdsStatus;
    Index dropped.
    Session1>Then try again:
    Session1>SELECT taxid
      2  FROM   taxids
      3  WHERE  locationid    = 111
      4  AND    NVL(STATUS,0) = 0
      5  AND    ROWNUM        = 1
      6  FOR UPDATE;
         TAXID
        100101
    Session1>
    --> Session 2 hangs again until
    Session1>BEGIN
      2   UPDATE taxids SET status=1 WHERE taxid=100101;
      3   COMMIT;
      4  END;
      5  /
    PL/SQL procedure successfully completed.
    Session1>
    --> At which point in session 2:
    Session2>SELECT taxid
      2  FROM   taxids
      3  WHERE  locationid    = 111
      4  AND    NVL(STATUS,0) = 0
      5  AND    ROWNUM        = 1
      6  FOR UPDATE;
         TAXID
        100102
    Session2>Proves nothing, Non-deterministic ROWNUM you say.
    Then let's reset, recreate the index and explicity ask then for row 100101.
    It should give the same result as the ROWNUM query without any doubts over the ROWNUM, etc.
    If the original behaviour was correct, session 2 should also be able to get 100101:
    Session1>SELECT taxid
      2  FROM   taxids
      3  WHERE  locationid    = 111
      4  AND    NVL(STATUS,0) = 0
      5  AND    taxid         = 100101
      6  FOR UPDATE;
         TAXID
        100101
    Session1>
    --> same statement hangs in session 2 until
    Session1>BEGIN
      2   UPDATE taxids SET status=1 WHERE taxid=100101;
      3   COMMIT;
      4  END;
      5  /
    PL/SQL procedure successfully completed.
    Session1>
    --> so session 2 stops being blocked and:
    Session2>SELECT taxid
      2  FROM   taxids
      3  WHERE  locationid    = 111
      4  AND    NVL(STATUS,0) = 0
      5  AND    taxid         = 100101
      6  FOR UPDATE;
    no rows selected
    Session2>Of course, this is how it should happen, surely?
    Just to double check, let's reintroduce ROWNUM but force the order by to show it's not about read consistency at the start of the statement - restart should prevent it.
    (reset, then)
    Session1> select t.taxid
      2   from
      3    (select taxid, rowid rd
      4      from   taxids
      5      where  locationid = 111
      6      and    nvl(status,0) = 0
      7      order by taxid) x
      8   ,  taxids t
      9   where t.rowid = x.rd
    10   and   rownum = 1
    11   for update of t.status;
         TAXID
        100101
    Session1>
    --> Yes, session 2 hangs until...
    Session1>BEGIN
      2   UPDATE taxids SET status=1 WHERE taxid=100101;
      3   COMMIT;
      4  END;
      5  /
    PL/SQL procedure successfully completed.
    Session1>
    --> and then
    Session2> select t.taxid
      2   from
      3    (select taxid, rowid rd
      4      from   taxids
      5      where  locationid = 111
      6      and    nvl(status,0) = 0
      7      order by taxid) x
      8   ,  taxids t
      9   where t.rowid = x.rd
    10   and   rownum = 1
    11   for update of t.status;
         TAXID
        100102
    Session2>Session 2 should never be allowed to get 100101 once the lock is released.
    This is a bug.
    The worrying thing is that I can reproduce in 9.2.0.8 and 11.2.0.2.

  • 0CRM_OPPT_H  (Transaction RSA3 gives wrong result)

    Hi gurus,
    <b>0CRM_OPPT_H  (Transaction RSA3 gives wrong result)
    BBPCRM 4.0
    BW 3.50 version</b>
    I had enhanced the structure "crmt_bw_oppt_h"
    and also written a BADI to populate Opportunity header status.
    But when I run extract checker RSA3 for CRM data,
    I get wrong number of records.
    I am having 95 records for Opportunities header data.
    Data Records / Call = "100"
    Display Extr. Calls = "10"
    Above settings, I am retrieving only 61 records.
    <b>Data Records / Call = "1"
    Display Extr. Calls = "200"
    For the above settings in RSA3,
    I am able to retrieve 95 records correctly.</b>
    The problem is that in RSA1 transaction of BW 3.50 server also,
    61 records are being loaded from CRM server.
    <b>Could this be a Cache memory problem,
    Are any of my BASIS settings a cause for this problem?</b>
    Any help is really appreciated and will be rewarded.
    Thanks,
    Aby Jacob

    Dear Friends,
    <b>I had to do a small correction in my BADI code.
    I got a solution from Online SAP HELP portal.</b>

    Notes on BADI Usage
    ====================
    The instance generated through the factory method should be declared
    as globally as possible or generally be passed as a parameter
    to ensure that the initialization process must be run as rarely as possible
    – just once would be best. In no case should you discard the instance as soon as
    it is generated or repeatedly run the initialization process in a loop.
    Within the adapter class interface,
    required database accesses are buffered locally,
    so that each access is executed once only.
    However, repeated initialization makes
    the buffer useless and dramatically reduces performance.
    Due to the local buffering, you can call Business-Add-In methods
    without having to expect considerable performance restrictions,
    even if no active implementations exist.
    Also, if the definition of the Business-Add-In is filter-dependent,
    a single instance is sufficient.
    However, you should not do without initialization altogether.
    Even if you could call static methods of the implementing
    class of the Business-Add-In implementation without an instance,
    you would lose the benefit of performance improvement through
    the Business-Add-Ins and the possibility of multiple use.
    If you switch the method type in the interface from the static method
    to the instance method at any time in the future,
    many code adjustments are required.
    In addition, you can no longer use default code that is provided.
    <b>Many Thanks to ROBIN
    and the whole SDN team</b>
