• 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 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:

  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;

• Determine if an integer is a floating-point number

  I want to create a program that when an integer is entered in the digital constant, a floating-point number with zeros to the right of the decimal point lights up the LED on the front panel. The LED remains off for any other floating-point number. I know I want to use a ride to the nearest function, but don't know where to go from there.

  You want to say CONTROL, right?

  You just need a type of rounding.  No matter if round you upwards or downwards.  If you just around and then compare the entry to the rounded value.  If they are equal, you turn on your LED.  So all you need is a digital control, 2 functions, and a boolean flag.

• Decimal in Floating point with cookers

  Hello

  I am wanting to convert a decimal value to be implemented at the scale of a floating point value.

  For example.

  a decimal value from 0 to 20000 where half is considered to be the zero point. Then share values and on the other of this average value are considered postivie or double negative (0-10000 considered negative, 10001 to 20000 considered as positive). Then, the resolution of each decimal value is compared to a predefined scale.

  Don't know how to do in this regard.

  Any help is much appreciated.

  Hello

  I hope I got everything you wanted.

• floating point No. the chain with the same precision

  I use "format string" to convert floating point No. to a string. Most of the numbers have a single decimal digit, so I use '%^0.1f' in the format in the connection string. But for our whole. like 150, it gets converted to 150,0. I want to avoid this, such that the chain looks exactly like the No.... What should I change?

  Use %#0.1f as your format string.

  Read the help file on the format codes.  The sign # told him to truncate the zeros.

• 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.

• Qosmio F50 - Webcam Error - Invalid floating point operation

  Hello

  I have a Qosmio F50 (4 weeks) problem is after two weeks webcam stopped working * not valid floating point operation *.
  I have to close the program via the Task Manager, * software camera Wizard does not *.

  Have you tried next.
  Update all drivers, System Restore

  Toshiba help line after all the efforts suggest all reinstall them it is aggressive for me, because he would lose some software on the laptop that I had to transfer old PCs and had to plead with some software companies to transfer (as a single license etc.).

  If someone else has had this problem and is there a simple solution

  Will be

  Hmm, you could remove the software of the webcam of the system and could remove too the webcam from the Device Manager.
  Then you could clean the operating system using the CCLeaner

  This software is free and it can clean the registry and the system. I use it very often.
  Then restart the laptop and try to reinstall the software of webcam again.

  Good luck

• compare arrays of floating point

  Hi all

  I have a table of 2_D as

  1 0,0119

  2 0.0140

  3 0.0157

  up to 50 items.

  and the second picture is as

  0.0137

  0,0153

  0.0156

  up to 20 items.

  I need to compare second table with the second column that is the first table floating-point numbers . Find 20 items in table 1 that are as close as possible (maybe not exactly equal) to the 20 items listed in table 2.

  and return the corresponding values for the colors n ° 1 in table 1.

  ex. - 0.0137 will be compared with the entire table 2.

  He'll find 0.0140 and we get part 2.

  0,0153 next will be compared and so on.

  Final result will be a 1 d array with values of col 1 only.

  Help, please.

  It is confusing that name you the 2D file P1.txt and the 1 d P2.txt file.

  It seems simpler to use "worksheet file read" to read the two files.

  The mistake you make now is to create the table 1 d with the default tab as the delimiter. He reads only one, because there is no tabs in the file. All you need to is change the newline delimiter. It is what it is!

  

  Now, it seems to work perfectly, please test.

• BUG: Large floating point numbers convert the wrong integer

  Hello

  When you use the 'balls' conversion to convert integers to SGL, DBL and EXT there are certain values that convert evil. An example is the 9223370937343148030 integer that can be represented exactly as a SGL (and therefore exactly as DBL and EXT as well). If you convert this I64 you get 9223370937343148032 instead, even if the correct integer is in the range of an I64. There are many cases similar, all (I noticed) at the wide end of the ranges.

  It has nothing to with the integers can be represented exactly as a floating point value or not. This is a bug of authentic conversion you mind.

  See you soon,.

  Steen

  Hi Steen,

  Thanks for this identification. I confirmed the EXT to U64 conversion problem in simply trying to make a round trip on a xFFFFFFFFFFFFF9B0 of value U64 EXT and back, is xFFFFFFFFFFFFFFFF as well (and the intermediate value in EXT is correct).

  The problem seems to be limited to integer values with the upper part of 53 bits set, as well as all of one or more of the 11 lowest.

  I have reported this (#396305), as well as the limited display accuracy questions (#396337).

• floating point to hexadecimal string

  Hello

  Is attached a screenshot of what I'm trying to do.

  The equation that I in the formula box basically is supposed to enter a number between 30 and 100 (which represents the intensity percentage) and he will give a value in which when converted to the spell and fed in my instrument will give the corresponding intensity in floating-point (ie. 30% if I had entered 30 as my x in the formula) I need. Thus, for example my lowest intensity (30) would give me a decimal value of 239 of the formula which is "EF" in hexadecimal.

  This code does not work for some reason any. If I replace my conversion function of formula and hexadecimal, with only a simple chain control and display of spell and EF entry switch and feed it into the instrument intensity makes the adjustment to 30%! But I prefer to use the scale bar instead which does not... Can someone please tell me if my conversion function is messed up or something.

  Thank you!
