• Division by zero weird problem on HP 8200 Elite SFF

  Greetings,

  I posted my message here, it appears now that my problem is hardware specific.  My machine has the following specifications:
  
  HP Compaq 8200 Elite SFF
  Intel Core i5-2500 Duo @3.3 GHz processor
  8 GB memory

  Windows 7 x 64

  (I can provide more details if necessary)

  This has been me puzzled for more than a week now!

  We have an application where we lack in a division by zero. That request is deliberately built to raise exceptions in this case, with a call to the function _controlfp_s for edit masks on floating point exceptions.

  Now, when you run in a division by zero pretty much all of our machines, Visual Studio 2005 debugger breaks in the right place in our source files. However, on this machine, the location of the break is in every sense and seems to be unrelated to the real cause of the failure. So as a test, I built a simple win32 C program with just the following lines of code:

  int main (int argc, char * argv [])
  {
      float temp1, temp2, temp3;
      unsigned int control;
  
      _controlfp_s (& control, _EM_UNDERFLOW + _EM_INEXACT, _MCW_EM);
  
      Temp1 = 1.0;
      Temp2 = 0.0;
      Temp3 = temp1/temp2;
  
      return 0;
  }

  On all these 'good' machines, the code breaks when the temp3.  Among the other machines tested successfully, I had various hardware and operating systems, including Server 2008 R2, Windows XP x 32 and Windows 7 Pro x 64.  However, on this machine, the code stops at:

  C:\Program Files (x 86) \Microsoft Visual Studio 8\VC\crt\src\tidtable.c

  function:

  __set_flsgetvalue()

  In reviewing the records I have change the assembler code, everything seems fine until I hit the "ptsps" statement... then all records seem to be messed up (vs research as expected on a good machine). When comparing the stack on the good vs. bad, I also see entries of pile on the wrong machine, I don't see a good...

  Now... Here's what I did to solve problems:
  1. a disc image of the original disc HP on a hot spare and the original picture restored.
  2. only installed Visual Studio 2005 Pro - portion of C++.
  3 - tested above, code has always failed.

  4 - update all service packs Windows and tested above code.  Failed.

  5 - update all service packs, the Studio 2005 and tested above code. Failed.

  6 uninstalling all the bloatware and tested above code. Failed.

  7 - updating the BIOS and firmware and tested above code. Failed.

  8. install Visual Studio 2010 and tested above code. Failed.

  Then... I decided to take my spare disk image and install it on a similar, but a little older HP computer that we have, which has the following specifications:

  HP Compaq 8000 Elite SFF
  Intel Core Duo E8400 #3 GHz
  4 GB memory

  I went through the process of installation very well, even though she used the typewriter 8200 recovery partition.  On this machine, I simply installed the operating system and Visual Studio 2005 Pro - portion of C++.  No service packs not whatsoever (even if the Studio 2005 requires an update for 'vista') and the code worked as expected!

  So, that leaves me about almost everything but the material!  Also note that I tried to disable several processors and all optimization of the BIOS on the 8200, without success.
  
  I don't see anything else I can try... Please help!

  Wow!

  After the posting of this message to a friend... He found a document showing very similar symptoms on some of their CPUs from intel... I then found the exact document who applied to our specific processor (intel i5-2500) here:

  http://www.Intel.com/content/dam/www/public/us/en/documents/specification-updates/2nd-Gen-core-desktop-specification-update.PDF
  
  See Erratum BJ1

  This article describes pretty much exactly what I run into!  (Seriously), I never thought this would be a problem at THIS level!

• CVI division by zero defects

  Hello

  I use NI LabWindows CVI 2012.

  I have a piece very simple code:

  Double a = 4/0;

  This piece of code, I would like to return NaN, or at least do something that isn't to stop the execution on the compilation.  "Is there a way to turn NaN handling functionality or add an exception for the compiler that said: if division by zero is found, returns zero" or something?

  Here, any help would be greatly appreciated

  Hello

  It's probably doing an entire division and then by converting the result in duplicate.  Division by zero with an integer will crash your application.  I would try this:

  Double a = 4.0/0,0;

  If adding le.0 in the end tells the compiler that it is a floating point type, where division by zero is not as bad.  Moreover,.

  Double;

  a = NotANumber ();

  Can also do what you want.  If you want to check for NaN you can do something like this:

  If (IsNotANumber (a))

  a = 0.0;

• Mike 11 error: Floating Point of Division by zero error

  I use Windows 7 for running software MIKE11 . I used the same software to simulate the model in another Windows 7 PC operated and it worked correctly. But when I want to use the software in the PC, it returns me the error each time. How can I solve the problem?

  'Division by zero' errors are triggered by the application, not by Windows. You must ask the supplier for advice.

  Anyone has an idea why I would occasionally get the pop up window with the message "floating point division by zero" when you install a program on Windows 7?

• Division equals zero exception handling

  Hi all

  I'm new to this forum

  I created a trigger, but it does not work.

  DECLARE

  v_width INTEGER.

  v_height INTEGER: = 0;

  v_area INTEGER: = 6;

  BEGIN

  v_width: = v_area / v_height;

  DBMS_OUTPUT. Put_line ('v_width =' | v_width);

  EXCEPTION

  WHEN NO_DATA_FOUND THEN

  DBMS_OUTPUT. Put_line ("Division by zero");

  END;

  /

  
  

  
  

  However, I always get this error

  ERROR on line 1:

  ORA-01476: divisor is equal to zero

  ORA-06512: at line 7

  I can't debug. I need to deal with in the right way, all exceptions must be considered.

  The best solution is to never divide by zero in the first place, for example:

  DECLARE

  v_width INTEGER.

  v_height INTEGER: = 0; / * no doubt it is affected in any other way * /.

  v_area INTEGER: = 6;

  BEGIN

  IF v_height > 0 THEN

  v_width: = v_area / v_height;

  DBMS_OUTPUT. Put_line ('v_width =' | v_width);

  ON THE OTHER

  Dbms_output.put_line ('v_width is undefined');

  END IF;

  END;

  /

  Also, don't handle unexpected exceptions with nothing but debug output - protect against them, manipulate them in a meaningful way, or allow them to be propagated to the caller.

• Division by zero error.

  Hi all
  I get division by zero error in one of the reports that has been developed by one of our programmers. I think that this can be easily corrected in decoding or using a Case statement. I'm not sure how to use it below scenario.

  You try to do the following?

  (1) if spread_miles_total is set to NULL, use instead 1.
  (2) if spread_miles_total is not null and is equal to 0, then use 1.
  (3) if spread_miles_total is not null and is equal to 0, then retains its value.

  If so, then use the CASE expression as follows-

• Calculator simple division by zero help

  Hello, I'm doing a simple calculator with four basic operations. I want an LED light up when I'm dividing by zero. However, if I divide by zero, the LED lights up, and then when I switch to another operation, the LED stays on until I turn to 'divide' and the denominator is not zero. Can someone help me with this problem? Thank you. My VI file is attached.

  ... or just thread out from the case of the divide and set the tunnel exit to "use default if thread continues. It turns on only if the divide operation runs AND the divisor is zero. If can be skewed (off) in all other conditions.

• Handful of division by zero error in SQL

  Hello
  
  
  a few messages back, someone asked about how best to manage divide them by zero.
  
  Can I come back to this topic with, what is the best way to manage divide them by error in SQL without repeating the code...
  
  What I have in mind is often divided by error appears as the result of a long formula calculation - and trying to bury a long a long calculation formula in a case statement gives you an extremely long result, but is not ideal for the maintenance of the code.
  
  Encapsulating the manipulation in a function is not great for performance reasons.
  
  
  So is there a simple way to do the equivalent of (pseudo)
  
  
  Select IFerr (real / (RidiculouslyLongConvulutedFormulaHereWhichSometimesYieldsZeroValues), 0) of the double
  
  Where IFerr works as NVL - except that it gives 0 when the result is a wrong number or the result otherwise?
  
  
  
  Thank you
  
  Robert.

  Hello

  a few messages back, someone asked about how best to manage divide them by zero.

  I saw this thread, but it mentions the NULLIF function?

  You can apply it to each denominator in your formula, so it returns NULL in which case it is set to 0.

  For example,.

  with t as (
   select 1 numerator,
          0 denominator
   from dual
  )
  select numerator/nullif(denominator,0) as div
  from t;
  

• ORA-01476: divisor is equal to zero

  Hello
  To avoid the error oracle ORA-01476 (in sql, pl/sql not) I check the divider first - so it don't not to zero - and then make the division.
  For example:

  with sample_data(n1, n2) as
  (select 6, 4 from dual union all
   select 8, 0 from dual)
   select case when n2<>0 then n1/n2 else 0 end
    from sample_data
  

  Is there another way to avoid division by zero error?

  
  I ask this question because, recently, I've been faced with a situation in which I got a part of the SQL like this:

  ...
  case when dxy+dey+kty+kay-kts<>0 then round(100*(ypol/ sum(case when eidos<>'1' then dxy+dey+kty+kay-kts  end) over(partition by ylik_cd)) 
  .....
  

  But if I had a requirement that multiple "when" conditions should be included - as the divider - writing which precedes
  solution would be complex and prone to errors (in which case I forgot a "when" clause). For example if I had:

  .....
  round(100*(ypol/ sum(case when eidos='1' then dxy+dey+kty+kay-kts when eidos<>'1' and dxy=0 then dxy+dey+kty+kay end) over(partition by ylik_cd))
  .......
  

  
  Note:
  I'm using OraDb 11 g v.2
  

  Thank you
  SIM

  Hello

  Instead of

  CASE

  WHEN n2 <> 0

  THEN n1 / n2

  0 OTHERWISE

  END

  You can tell

  N1 / NULLIF (n2, 0)

  This returns NULL when n2 = 0, which is probably less misleading: return 0 in fact resemble the division could be made and n1 = 0.

  If you really want to return 0 if n2 is ZERO, then

  NVL (n1 / NULLIF (n2, 0))

  0

  )

  Unlike the CASE expression, this returns 0 when the n1 or n2 is NULL.

  If you really want the same results as the CASE expression gives you, then the CASE expression is the best way, i.e. repeat n2.  If n2 is a complicated expression, then you can calculate it in a subquery, so all you have to repeat in the expression BOX (in the Super-requete) is his name.

• Trying to write a script to custom for a formula of division calculation.    Someone knows how to do this?  I tried everything I can think of.

  I have a field that I need to reflect the quotient of two other fields as a percentage.    My only options under the 'value' are sum, product, average, minimum, and maximum.

  I got around this relative to subtraction problems by creating a new text box and one of the fields of multiplication by a negative.   I don't know what to do with to get my formula of division.

  Can anyone help?

  Need you (learn and) write JavaScript instead. It is more complex, for example, you want to test the division by zero to avoid an error. This is why it is not in the list of simple (don't) options.

• Calculation form: Division - Quotient and remainder

  This calculation of shape is possible?

  Between dividend in the to field user > user between divider in domain B > C field calculates the quotient > field D calculates the rest

  example 1: 100 ÷ B25 = C4 D0

  example 2: A90 ÷ B25 = C3 D15
  

  Of course, the only thing is to check that the divider is not empty or null, as the division by zero is not allowed.

  Basically, the C field calculation script can be something like this:

  var a = number (this.getField("Field_A").value).

  var b = number (this.getField("Field_B").value);

  If (b == 0) event.value = "";

  else event.value = Math.floor (a/b);

  Field D using the same code but replace the last line with:

  else event.value = (a and b %);

  Hello
  
  Yesterday was a great help by Frank et Al concerning a request for the increase of the % of the previous year
  
  SQL to get % increase in the amount of the previous year
  
  One problem that I'm faced with this is that if the specific 'exp_type' does not exist in the table for a given year, I get the "division by zero error.
  
  It works fine when there are values for all years. Is there a way to get around this? Maybe the value null or 0 but not raise an error. I tried to use NVL but did not work
  
  {code}
  
  
  WITH total AS
  (
  
  TO_CHAR (date_exp, 'YYYY') SELECT an
  SUM(CASE WHEN exp_type =:P1_YOY_PERCENT_LIST THEN exp_amt ELSE 0 END) AS Type
  Of exp_main
  TO_CHAR GROUP (date_exp, 'YYYY')
  
  )
  SELECT year 'year '.
  Type
  TO_CHAR ((Type/Type of NVL (LAG (Type) (any ORDER PER year)), * 100)-100, '999990') | ' %' "% increase.
  OF THE total amount
  ORDER BY year DESC
  
  {code}
  
  
  FYI - the: P1_YOY_PERCENT_LIST is just a value in the Apex that I use to allow users to select any 'exp_type' for who they want to see the increase in % of the previous year.
  
  Thank you
  Ryan

  You are actually providing the 0 value in the ELSE clause. If you leave just off of the ELSE clause, then SUM returns NULL when there is no line with the given exp_type.
  {code}
  Sum(case when exp_type =:P1_YOY_PERCENT_LIST Then exp_amt end) AS Type
  {code}
  There is always a problem if exp_amt can really be 0 or exp_amt can be a combination of positive and negative numbers which could total 0.

  {code}
  Of exp_main
  TO_CHAR GROUP (date_exp, 'YYYY')

  )
  SELECT year 'year '.
  Type
  TO_CHAR ((Type/Type of NVL (LAG (Type) (any ORDER PER year)), * 100)-100, '999990') | ' %' "% increase.

  The standard method to avoid division by 0 in x errors / when there may be 0 is
  {code}
  x / NULLIF (y, 0)
  {code}
  This returns null if y = 0. In your case, which would result in:
  {code}
  To_char ((Type
  / NULLIF (NVL (LAG (Type) (ORDER BY year)
  Type
  )
  0
  ) * 100
  ) - 100
  '999990'
  ) || '%' "% increase.
  {code}
  which guarantees that you will get the NULL value instead of the division by 0 error, but that means that the whole expression will be "%" when the number is NULL. If you really want the % sign in the set of results and not just the head, then use CASE, as Boneist suggested and cumulative Sven.

• Divide by zero problem

  Why n %3 or n MOD 3 return "Division by zero is not allowed.", if n == 0? (3 may be a number any).

  Used with numeric values actual/double modulo operator doesn't make much sense from a point of view of math in the first place because it is really intended to provide you with the remainder after integer division.

  ColdFusion still allows you to do this, but if the right hand side of the operator modulo is a numeric value real/dobule it will simply ignore the fractional part. In your case, it will be 3 MOD 0-> so division by zero error.

  This particular behavior is actually documented in the CF documentation as such.

  See you soon
