Problems of bit shift left in the node of the formula

Hello

Sorry, but my English is not good.

I am trying to run a bit left SHIFT in the node of the formula, but the left SHIFT does not work as I expected.

uInt32 parametro[5];
float32 valorAmostra;
int16 indiceAmostra;
uInt8 indiceResposta;
int16 controle;
int32 valor;
int8 i;

for(i=0; i<5; i++)
    parametro[i]=param[i];

valor = parametro[5]<<16 | parametro[4]<<8 | parametro[3];
controle = parametro[1]<<8 | parametro[0];

indiceAmostra = (controle & 0x3FF);
indiceResposta = (controle >> 10);

valorAmostra = valor & 0x7FFFFF;
valorAmostra = valorAmostra*(2.4/8388607);

   if((valor & 0x800000) == 0x800000)
      valorAmostra = valorAmostra*(-1);

the input param array is uInt8 type, because I saw in other topics that does not move with uInt8,

I copy the values in the array param to parameter , which is of type uInt32, but still does not work.

Test the input parameter with the following values:

[] param = {10,14,10,0,16}

the returned valorAmostra is 0,00117188 then it should be 0,300003.

Can someone help me please?

OLA,

Is um no bug no LabVIEW para esta operacao. Este bug devera ser corrigido em paid futuras. UMA Solução para esta down e use int32 ao investment of um ulnt32 um.

Any doubt please between let em.

Obrigado.

I studied the problem you are having, and it turns out that this is a bug that has already been reported and documented. The work around is to use int32 instead of uInt32.

Thank you.

    With the help of the bit-shift operator twice on the same line of code produces incorrect results.
    Workaround: Separate the operations of shift of two bits in two distinct lines of code.

    Reported Version: 9.0    Solved Version: N/A    Added the: 14/02/2012

    Could someone please explain what kind of construction causes such a question?

    I have not noticed problems again and not have not noticed or found a thread about it.

    Thank you.

    The reported scenario looks like this:

    unsigned int a = 1, b = 62;
    unsigned  long long result = 1ULL << a << b;
    

    The problem arises because of the temporary variable used when do two little is placed in the same line. This separation into two lines will produce correct results:

    unsigned int a = 1, b = 62;
    unsigned  long long result = 1ULL << a;
    result = result << b;

  • Left SHIFT key of the T40 reveals context/right click menu?

    Hello all-

    On my T40, on which I recently got properly installed, Windows 7 has a curious behavior:

    When I press the left SHIFT key, it works the same as if I had pressed the right button of the mouse.  It works otherwise, I.e., then its use to capitolize a letter in an e-mail, the letter is capitolized, but as soon as I let go of the SHIFT key, the context right click menu will then appear.

    It's extremely annoying, because I can't continue typing until I sailed out of the menu.

    I checked to see if the keyboard customiser utility is the cause, I have currently my left Alt key works as a button of Windows, but it does not ask this question.

    Anyone have an idea how I could go about fixing of this?

    Thanks in advance,

    G

    Too bad.

    Had the customizer of keyboard configured to use the time left as the key to the application key.  Duh.

  • Problem with text table: text align to the left in the table

    I can't try to get the text to align inside a table. I'm working on a document that has the body text indented to 12 mm. I discovered that the left of the table corresponds to the tabs and it remains fixed on the marks of the tab. I managed to get the first row of the table to align the text of body outside of the table and the table is positioned how want it to be, but I can't get the rest of the text to align with the first line. Here is a screenshot of the problem:

    Screen Shot 2015-11-24 at 5.43.27 PM.png

    I did it by changing the removal of paragraph to 12 mm and by changing the withdrawal of first line to 12 mm. I've been fiddling with the tabs and other settings, but I can't not all aligned text. Is there a way to align it all without creating a separate or rectangle text box?

    Best regards, Kirk

    Thanks for your help. I just found out that I was using a paragraph style just outside the table who had no hyphen, and it prevented me to rethink the table. Your method worked, but only in the document with examples I showed you. (I did separate because I work on the project of sensitive information) and when I pasted in my working paper, the table is always aligned to the left margin. I then checked the paragraph mark immediately after the table, and there was my problem. I just changed the paragraph style to the same as the outside of the body text. This caused the table to align the body text without affecting the text inside the table.

    Best regards, Kirk

  • Hi, I have a problem in the installation, how to install acrobat 8.1 pro in 64-bit Windows 7 Enterprise is existing in Windows XP.  I just want to transfer the license Adobe pro 8 Windows 7 64 bit. What is the procedure?

    Hi, I have a problem in the installation, how to install acrobat 8.1 pro in 64-bit Windows 7 Enterprise is existing in Windows XP.  I just want to transfer the license Adobe pro 8 Windows 7 64 bit. What is the procedure?

    You need to install 8 AA on the new OS with your current S/N (the license allows 2 installs). After the installation, do all the updates if you expect any chance of 8 AA to run on the system. If the updates will be installed not in the menu help, then go to ftp://ftp.adobe.com/pub/adobe/acrobat/win/ and install updates in the order. People seem to have been successful with 32 - bit systems and some have reported success with a 64 bit system. After installation, print something to the Adobe PDF printer to make sure it works. If this works, you should be in good shape as printing treat the bottleneck. There is a solution, but you shouldn't have it.

    If all works well, then go back to the old machine and disable this installing and uninstalling. Don't forget that your configuration is not supported by Adobe. It seems with every new version of Windows, MS seeks to make the user to upgrade the other hardware and software for compatibility. There may be legitimate reasons for this action, but the game just seems to be Ms.

  • model pages shift slightly to the left when it is downloaded

    Hello

    I'm fairly new to dreamweaver and I am having trouble trying to get my page template to open correctly. On my index page, I created editable regions and saved the page as a template. I opened the new model choose one that I just created. I add text and save it. When I download all the files and click on the tab to connect to my page of model, the model opens but it shifts sligtly to the left. What am I I do that could be the cause. Thank you, Owen

    You'd change the menu on the model page, since you want that these changes propagatge to all pages of the child.

    See the page of the template itself is still completely editable.  It's the child pages that are being modified/no editable regions.  And it is only the changes that you make to non editable model regions that spread to the child pages, otherwise you could ever have unique content on the child pages.

  • Problem with key 'Shift' Lenovo Y530

    I bought a Lenovo Y530 recently with Windows Vista 64-bit.

    I'm having a problem with the 'Shift' key as they seem to be related to some sort of function hotkey or short cut:

    Left Shift-> on a notebook left SHIFT press types "] yt ' and active / turns off the Capslock. He also started a search or find on the desktop

    Right shift-> by pressing the right shift key prints «...» MV' on Notepad and done something funny

    It is therefore impossible for me to use this laptop. I tried following things so far:

    1. disable the shortcut keys in the Intel Graphics toolbar

    2. all controls 'ease of use '.

    It seems that Shift key everything except what it is supposed to do.

    Any help will be greatly appreciated.

    Thank you

    Hello

    I think that I found a solution to the problem. Although it sounds randomly - but it works for me.

    It just open wordpad and begin typing shift with other keys at the same time and randomly - very random and very fast. Hmm and well, it suddenly begins to work properly. It's pretty random and the problem is back, but he always solved with this... well "method" (if you can call it a 'method').

    I have not had the problem for a few months now. So, it does not. It is not a hardware problem safe - and nothing to do with the access keys.

    It will be useful.

    Thanks for any help

    Hello

    > I am disappointed to see the SHIFT key (left) and the CTRL pressed, causing the screen to go black intermittently when you type my blog...

    What does this mean exactly? Press SHIFT and CTRL button turn off the display, and you are not able to see anything on the monitor?
    Is this good?

    Have you checked if this happens with the help of an external USB keyboard too?
    If this isn't the case, I guess that your keyboard is malfunctioning and needs to be replaced.

    One of my friends had a problem with my keyboard. The cursor jumped around and some characters are displayed two times this could be resolved by the BIOS update I m do not know if your laptop uses the latest version of the BIOS, but you can check this too.

  • UP3214Q REV02 - all windows resized to 1024 x 786 and moved to the top left after the power monitor cycle

    Hello

    I recently got a model REV02 my REV01 developed a fault. However, it seems as if these screens maintain their unwilligness to allow us to save energy by turning off the screen when you need a bathroom, coffee break or something else. Whenever you turn off the screen, then turn on again (be it a few seconds later, or minutes to hours later), all open windows will be resized to 1024 x 786 pixels and placed in the upper left corner of the screen.

    This happens on the Intel cards and nVidia (GTX780TI on 347.52, intel Hd4400 on 15.36.14.4080 drivers drivers). I went throug the playbook together to offer the GFX card, so reset screen, remove the drivers with uninstalling the driver and perform a drive clean reinstall, and swapping the cables (I have a bunch of cables apprived dell when they initially did not want to send me an A01 to set half of the image & had the A00 sleep problems). Happens DP1.1 and DP1.2 mode, and it happens 10 times out of 10.

    Anyone with a UP3214Q who sees this behavior as well? BTW, this is my 3rd unit of REVA02, they all exhibit the same behavior (exchanges were not made because of that, but it confirms that the problem is not related to a defective unit).

    See you soon

    It is a common problem among the monitors UHD, a lot of posts here about it - they take longer to wake up causing the driver GFX their definition to a safe lower resolution before them at their native resolution. The latest 14.2 AMD drivers seek to correct this problem, and you will probably see the same kind of difficulty in the future of the drivers from NVidia and Intel.

    In the meantime, if you use Dell Display Manager (DDM) and are comfortable editing the registry, try to add the "RestoreWindowLayout" value to HKEY_CURRENT_USER\Software\EnTech\DDM and set it to 1 (dword).

    You will need to have the latest version of DDM (b.1554) for this to work; Hold down the SHIFT key while right-clicking on the DDM notification icon and select "Check for new version" in the context menu.

  • Windows 7 Pro (64 bit) has no install the AHCI Driver

    When I built my current computer system in May 2011, I have not encountered this problem with installing 64-bit Windows 7 Pro on the new 500 GB Western Digital HARD drive.  In fact, I installed Win7 three times (to wipe the drive with DBAN after the first and second installs) before I was satisfied with the third installation.

    Before the first installation, I configured the BIOS of card mother Gigabyte GA-890FXA-UD5 (Maj) SATA AHCI (with SATA 3.0) and copy the driver AHCI of CD Gigabyte on a SanDisk Cruzer USB (4 GB).  The GA-890FXA-UD5 (revision 2.1, version of the F6 BIOS) has an AMD chipset.

    During each installation, the Win7 Installer reported that she could not find a HARD drive and offered the option to load a driver.  I used this option, and the installation program displays a dialog box with whom I sailed the Cruzer to select AHCI driver.  Each time, Setup loaded the driver with success smoothly.  Of course, I still have the installation of Microsoft Windows 7 Pro DVD, purchased with a full license of the retail.

    Example: two years later, after that I started to meet various problems for which I could find no cause, no resolution, I suspected malware or corruption of the registry.  To make a long story short, eventually I decided to erase the internal HARD drive once again, after you save the data files on an external USB HDD.

    Win7 Setup now follows the same routine, of course.  Except that now, it will fail to load the driver AHCI of the SanDisk Cruzer (!).  I've also removed the Win7 installation DVD, loaded the CD Gigabyte, sailed to the driver and selected.  The Win7 Installer is always not load.  In addition, before you run the Win7 Installer for other attempts, I connected the USB HDD external and sailed to a copy archived AHCI driver on it, but Win7 Setup could not load.  I have made many and repeated attempts, with all the storage media at hand, that contains a copy of the driver AHCI files, but not joy.

    For what it's worth, I also ran the software on the repair disk I did shortly after installing Win7 Pro, and he couldn't load the driver AHCI of the SanDisk Cruzer with CD Gigabyte, respectively.

    Then I reconfigured the BIOS of the motherboard to SATA IDE (with SATA 3.0) and rebooted the system.  You might think that Win7 Setup would have a suitable driver for the AMD SATA IDE, since she has one for the reader to optical disc Samsung DVD-Writer (obviously), but it did not find a HARD drive.  Then I sailed in the appropriate driver AMD x 64 on the CD of Gigabyte IDE files, but Setup cannot load it, too.

    Question: why Windows 7 Pro 64-bit Setup does not install the driver AHCI, and what can I do about it?

    Hello

    Thanks for posting your query on the Microsoft Community.

    AHCI (Advanced Host controller) makes the NCQ (Native Command Files) with connection to warm or hot swapping through host controllers SATA Serial - ATA possible; Vista was the first to offer this feature. The problem with AHCI is that it must be enabled in BIOS before the installation of the OS. After installing the operating system will disable the PC. The reason why Windows disable the AHCI drivers not not needed during installation.

    I suggest you activate the AHCI after installing the operating system if you already enable AHCI in the BIOS, when you installed the operating system.

    6. close the registry editor.
    7. now you will need to reboot the PC and go into the BIOS and enable the AHCI. When Windows starts, it will finish installing the AHCI drivers.
    8. you will need a final restart to complete the process once the drivers are installed.

  • now shift aligns with the weird angle

    I'm in the middle of creating a logo, that is overdue, and suddenly I can't make a straight line. When I hold the SHIFT key while dragging my line that she break, but not right! The little info box I made dragging the line (with shift) readings 0º or if I move it down a bit he clings to the 315º, but this obviously isn't 0º is snaps to the. I can't make even a straight square or rectangular face with SHIFT, they all align with a weird, asymmetrical angle. Some people have the direct problem form where shift does not produce a wink to all... mine IS slam & SAID 0º, so it must be right, but it is not at all. Same ellipses are spread when I hold SHIFT. It's like the grid when haywire! And if I'm eyeball to a straight line the little info tag says it's to 338º, instead of 0º.

    I created a new document, and that one works fine. Maj snaps my straight line & all my squares and rectangles and ellipses are perfectly straight. So, what was wrong in my original file? A I touched a button command that I'm not familiar with which screw up in my network? Below you can see what a change of product portfolio you can see the tag info I drag my line while now shift that's snapping at 0º, it says. THAT looks like a straight line of 0º?

  • Problem with "resolution and size of the work exceeds the maximum that can be rasterized.

    Hi all

    OK, I've created a document 162,7 "x 90.6" (work plan) for a design I design. The document was created using all the flaws - I think that's where I was wrong. Illustrator is now telling me that "the combination of the size of the work and the resolution exceeds the maximum that can be rasterized" after I opened the document and when I try to add a shadow to what whatever.

    Other than vector graphics, I created in illustrator, I only have 3 180ppi and 4 300 PPI pictures tranfered just behind the camera photograpers.

    I chose:

    1 "print document" in the initial startup window.

    2. I got the size of the artboard, purge and left control the 'pixelation effects' "high (300ppi).

    I think that to let the adjustment effects of pixelization at 300ppi, where is the problem.

    What I need to create a new document or I can fix it already exists?

    Illustrator is 32-bit only and is limited to 3 GB or RAM usage, it is more a limitation to a bug.

    t has a limit to the size of a tiff file that I can export for example and you can have reached this limit.

    Try opening it in Photoshop before you start all over, and then save it in psd or tiff.
