• 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;

• Simple division in Acrobat field

  I have a field in Acrobat I type the number of homes sold in the past 90 days, it will always be a whole number.  I formatted the field as a number with 0 decimal places.

  I have another field I want to just take this field and divide by 3 to give me the average number of homes sold per month for the last 3 months.  I have this updated field shaped like a number to 2 decimal places.

  Also, I get the error "the value entry does not match the format of the field [field name]" I understand is a division by 0 error.

  I'd like a quickie script that solves both the error and the fact of simple division.  I don't know anything about JavaScript.  I was just hoping scoring singles I could set FIELDNAME/3 and which might work, but apparently not.

  Any help would be GREATLY appreciated.  All the answers I found were calculation scripts that held two domain names different accounts, but nothing to do with a simple fracture of integer.

  Thank you!

  John

  The field for the simplified field notation names cannot begin with a number.

• 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 %);

• 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.

• Division by zero floating-point

  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?

  See if they give you ideas as to what could be the cause.

• Division by zero at t.

  Hi all

  I have a problem with QoQ when the division is zero. I usually use nullif in oracle queries, but it's not allowing in t/t.

  How can I solve this problem?

  Example code:

  < cfquery name = "qrySum", dbtype = "query" >

  Select "Item01" as DESCR

  < cfloop from = "2011" to index "2016" = "o" = >

  sum(FY_#y#) as FY_ #y #.

  sum(COST_#y#) as COST_ #y #.

  , sum(COST_#y#) / sum(FY_#y#) like PERC_ #y #.

  < / cfloop >

  Group of DESCR

  < / cfquery >

  where for a year 2014 the sum (FY) = 0 and sum (COST) = 0

  Thank you

  Playing sometimes dumb is the way to go. How about this:

  Sum (FY_2011) as FY_2011, sum (FY_2012) as FY_2012, sum (FY_2013) as FY_2013, sum (FY_2014) as FY_2014, sum (FY_2015) as FY_2015, sum (FY_2016) as FY_2016

  Select "Item01" as DESCR

  , #FYsum.FY_2011 # as FY_2011, #FYsum.FY_2012 # as FY_2012, #FYsum.FY_2013 # as FY_2013, #FYsum.FY_2014 # as FY_2014, #FYsum.FY_2015 # as FY_2015, #FYsum.FY_2016 # as FY_2016

  sum (COST_2011) as COST_2011, sum (COST_2012) as COST_2012, sum (COST_2013) as COST_2013, sum (COST_2014) as COST_2014, sum (COST_2015) as COST_2015, sum (COST_2016) as COST_2016

• 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.

  Just a hunch, but the version of your database includes analytical functions?

  In all cases, the original query fails if spread_miles_total is set to 0, as follows-

  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-

• Why perform a simple division differently from any phone or hand held calculator calculator MS (in the menu 'START')?

  I calc 0,0299 / 365 and get 8.1917 on my pc.  I have 0.000081917 on my phone + held in the hand.

  You must have a different calculator on your PC that I do.  When I do the calculation, the result is:
  8.1917808219178082191780821917808e - 5

  The "e-5" in the end, of course, means moving the comma 5 digits to the left...  The answer is basically the same.

• Completely random behavior for script of division. Need help :)

  Hi people,

  I put a lot of hard work in a form for a client (with the much appreciated help of people on these cards) and I thought it was full but...

  The customer got my attention on a seemingly random behavior for 2 fields on the form.

  I have no knowledge of Javascript but, based on the research online, I came with a custom script. I've rechecked the script but can't understand why random behavior would occur.

  Here are the scripts for 2 fields:

  Basic loan

  ----------------------------------------------------------

  (function () {}

  Get the field values as numbers

  var numerator = + getField("Loan_Amount_3_L2").value;

  denominator = var + getField("Bank_Value").value;

  Do the math if the denominator does not evaluate to zero

  If (denominator! == 0) {}

  Event.Value = numerator / denominator.

  } else {}

  Event.Value = "";

  }

  })();

  Ready

  ----------------------------------------------------------

  (function () {}

  Get the field values as numbers

  var numerator = + getField("Total_Loan_2_L2").value;

  denominator = var + getField("Bank_Value").value;

  Do the math if the denominator does not evaluate to zero

  If (denominator! == 0) {}

  Event.Value = numerator / denominator.

  } else {}

  Event.Value = "";

  }

  })();

  ----------------------------------------------------------

  And here's screenshots of the completely random behavior:

  Below if we begin to enter numbers... and things look OK. $500,000 divided by $500,000 = 100 percent

  

  Below, we add more numbers. Now, things are unhinged. Here, the result of 92% is incorrect. $400,000 divided $ 500,000 must be equal to 80%.

  

  Then below the plot thickens again when we add more numbers. Here the basic loan value is correct at 80%, but the end of loan value is not correct. The ready value must be equal to 81% - not 80% ($ 405 000 divided by $500,000 = 81%)

  

  As a side note, if I do a simplified field notation, the calculations seem to work. The reason why I do not have a simplified field notation, however, is that I get those annoying WARNING come up:

  Warning 1: "The value entered does not match the format [Base_Loan_to_Value_Ratio_LVR_L2]"

  Warning 2: "The value entered does not match the format [End_Loan_to_Value_Ratio_LVR_2]"

  (The fields mentioned in these warnings are the destination fields that produce the above incorrect percentage values).

  Could someone please identify what is happening here? Why is there such a seemingly random variation? And how can I solve this problem?

  Thank you

  Did you check the order of calculation of (different from the tab order) field to make sure it makes sense that the form?

• 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;
  

• I can't play videos from a simple site like CNN - HELP / Windows 8

  Hello

  Some settings have been changed on my computer.  I don't know what I did.  I upgraded to 8.1 to see if it would fix the

  problem of not being able to play simple video on cnn.

  Whenever I try to read the CNN video, it says: "cannot display the content checking internet connection.

  It is not a problem with internet connection, otherwise I would not yet be able to get on CNN.

  Why I can't play video?

  Help, please.

  Do I need Adobe? Flash?  I have no idea what happened.

  Thank you

  I would try first just reset your Internet Explorer, it can probably solve the problem.  Here's how:

  Since you are using Windows 8.1, you will need to use the "manual" section of these instructions.

• Calculations of edition and checkbox help (JavaScript novice needs help)

  Hey everyone, so I'm having a few problems with the implementation of my adobe calculation using the fields. I don't know a lot about the use of JavaScript so that any help would be appreciated.

  1. This is my first problem in simplest form:
  • I have a field (F1) and a field that uses F1 to calculate a result (F2).

  F1 = 18

  F2 = ((F1-10)/2) (which in this case, the answer is 4)

  Now where I will have questions, it's that I need a symbol of the addition to appear before the "F2" (the result here would be + 4)

  I took a picture of how I did it in Java where it would be useful to answer the question:

  

  2.

  My second problem is that I want a checkbox to change the values if it is pressed. I'm still lost on this part, but all this I want to do is the following:

  • If the checkbox is unchecked nothing happens. If the box IS checked, then I would add 2 to another field. If the box IS checked that the + 4 would become a + 6, so using the above problem.

  Now since this is my first time editing an adobe form and using the fields for calculations I'm quite lost on the boxes and what script would go inside my custom fields properties calculation script. I don't know much outside of what I learned today about JavaScript so that any help would be greatly appreciated.

  I thank in advance anyone who responds.

  The custom for the field F2 calculation script could be something like:

  (function () {}

  Get field values

  var v1 = getField("F1").value;

  var v2 = getField("CB1").value;  Check box value. "Off" otherwise we'll pick

  Add 0 or 2 depending on the value of the checkbox

  var v3 = v2 = "Off"? 0: 2;

  Perform the calculation

  var result = (v1 - 10) / 2 + v3;

  Add a '+' if positive

  If (result > = 0) {}

  result = '+' + result;

  }

  Set the value of this field

  Event.Value = result;

  })();

  This could be simplified, but it should help you get started. Replace "F1" and "CB1" with the actual names of the fields.
