Bug in the Windows 7 calculator

There is a basic bug in the calculator of windows 7 (only in the standard display)

Equation 1 + 2 * 3 the answer 9.
In fact, the answer should be 7.
If we play a little, we discover that he is simply performing operations on from left to right, and failing to perform the multiplication and division before addition and subtraction.
If I try the same equation in scientific display or programmer, you get the right answer (7)

Hello

The hierarchy in the basic calculator is from left to right is

1 + 2 = 3

3 * 3 = 9

The scientist and the programmer calculator use the hierarchy of mathematical operations
and the Standard Calculator treats 1 both functions in the order entered.

This has been noticed in many versions of the calculator.

I hope this helps.

  • The Windows 7 calculator is fake

    As we know all the tangens of 90 degrees is 1. This is what you get when you type 90 and press 'tanh '. No problems so far.
    Now if you do the reverse tangens of 1, you should get 90 degrees again. Is not! Just hit 'Inv', then ' tanh ^-1 '. He will give a weird number like 89,9999828051 etc.

    So much for the reliability of the Windows Calculator for geometry.

    I presented these 3 topics, which are bugs in the cmd shell. first they said I should introduce him to technet.  then they said I should present the msdn forums, although I don't see how it's appropriate, then told me I should post to Microsoft Answers, so I'm back to where I started.

    I suspect that these bugs may not affect only XP but the newer versions of windows as well.

    I have a XP Pro 32-bit and 3 GB of RAM, Pentium 4 HT 2.8GHz system (1 core, 2-wire).  It is a relatively new installation of windows, and I recently cleaned the CPU cooler.  I'm doing the repair of computers as my business and software development as a hobby.

    • do the hibernation twice in a row causes the need for a hard stop.  This is not good.  I should be able to do the overwintering without end.
    • Windows gets more unstable as time goes by, until I need a reboot after about a week or two of the race.  I wouldn't restart.  I don't want to restart. I need my development environment I need to put in place every time.
    • Windows gets slower and slower to react to the events of keyboard and mouse over time.  services.exe is apparently chewing 50% cpu for a few seconds so that this 'pause for the system' is happening.

    I agree with the response of Al Dunbar, posted to your thread in the TechNet forum.

  • How can we make the greatest Windows 7 calculator keys?

    It would be great comfort that we have the possibility to enlarge the buttons of windows 7 calculator. Personally, I'd rather have each button size 2 cm by 2cm.

    Most of the people not to click on the buttons, they just type the numbers on their keyboard instead.

    You can increase the size of all the buttons, including the Calculator buttons, if you want to.  To give this a try and see if you like, follow these steps:
    1 type dpi in your Start menu.
    2 - Click on the option that appears called make text and other items more or less
    3. fix the size you want, then click on apply to test.  You can always cancel it if you don't like it.

  • Bug in the sidebar of Windows 7 RTM

    Hello

    I've been using RTM of Windows 7 Professional x 64 and I noticed a very annoying bug with the sidebar.  I can reproduce 100% of the time by following these steps:

    1. Take any program window, and then drag the gadgets.  You may notice that the gadgets remain behind the window.
    2. Press the 'Show Desktop' button in the lower right.
    3. Restore any window or opening a new program and now try and drag it on the gadgets.  You may notice that the stay of gadgets are always on top of any other window.

    The only way to solve this problem is by enabling / disabling the "Show desktop icons" option (context menu in the office) and the new.

    I fixed it by restarting the computer... but it certainly isn't the only time when that happened.

    It just happened again not too long (was to kill sidebar.exe restart it...)

    Seems that something is randomly triggered.

  • Cannot change PopUp LOV width and height in version 4.2.5.00.08. I change the values of 450 400 in the Popup list template values (Section of the window), but my function genList0_f07_$ _row (), retains the same settings. Is this a bug?

    Hello

    I use APEX 4.2.5.00.08 to my app.

    I have a region of reports, where I display a column set. A column is the column attribute "display as" the value 'Popup LOV (LOV based query).

    I press the button to retrieve the LOV, I get a popup of 450 x 400 pixels.

    I go to the side of the model and navigate to "Popup list of values of model", where I can see in the section 'Window' attributes 'Width' and 'Height' value 450 and 400. I edit them and save them and there is nothing going on. I'm sure that the template belongs to my selected theme.

    I saw in the HTML source code that is the called function:

    <!--


    function genList0_f07_$ _row)
    {
    w = open ("wwv_flow_utilities.gen_popup_list" +)
    « ? p_filter ="+
    "& p_name = ' + escape ('f07') +.
    ' & p_element_index = ' + escape ('0') +.
    ' & p_elem_id = ' + escape ('f07_0000').
    ' & p_form_index = ' + escape ('0') +.
    ' & p_max_elements = ' + escape ("") +.
    ' & p_escape_html = ' + escape ("") +.
    ' & p_ok_to_query = ' + escape ('YES').
    ' & p_flow_id = ' + escape ('114') +.
    ' & p_page_id = ' + escape ('100201') +.
    ' & p_session_id = ' + escape ('16021544706004').
    ' & p_eval_value = ' + escape ("") +.
    ' & p_translation = ' + escape ('NO') +.
    ' & p_lov = ' +.
    ' & p_lov_checksum = ' +.
    ' & p_item_id = ' + escape('-683997768') +.
    ' & p_column_id = ' + escape ('25022622060292812'),
    "winLov,"
    "Scrollbars = 1, resizable = 1, width =400, height =450"); "
    If (w.opener is nothing)
    w.opener = auto;
    w.Focus ();
    }
    ->

    I see that the values has not changed. I also connected and disconnected. I am inclined to believe that it is a bug of the APEX.

    The only solution I think is to replace this function, which is NOT ideal.

    Thank you

    The parameters are generated only, nothing you can do about it because it does not use the model for these properties of the couple. Other things work fine for example the names of button or title window etc. I guess that, Yes, it is a bug. It's still there in the apex 5 too, I checked. The default values of the template do not match, the value in the generated code is always 400/450. So I guess it's pretty much a wait on 5.1.

    Here's a fun hack to make it work well on your page (works in apex 5 too, because the code is always the same). Put this in the execute on loading of the page section:

    (function(){
      var _open = window.open;
      window.open = function(){
        if ( arguments[1] === "winLov" ) {
          arguments[2] = "Scrollbars=1,resizable=1,width=500,height=700";
        };
        return _open.apply(window, arguments);
      };
    })();
    

    Change the settings to your liking. This will replace the existing window.open call, which is what the popup lov use and replace it with our own code. It does not interfere with other things. As the name of the new window is always "winLov" for the popup lov, it is the argument that is checked.

    During the call to window.open to open a new window with the name "winLov", parameters are replaced with your own version of it. The window is called as usual, using the stored reference.

    Edit:

    Yes, do not use the trick of resizing. My hack can be a bit tedious, but it's much less invasive for the end user (see open, bam, resize. "Even gets funky on multiple monitors). Also, this thing in the popup lov template will affect each lov popup that you use in the application, which is much less interesting than my specific page code.

    Edit2:

    I did a little digging in the source code, and I don't know why it does not work. Popup lovs are actually equipped to deal with it. My guess is that the parameters are recovered only after that the lists were generated, causing the package variables global to use their default values instead of model parameters.

  • bug: the windows are small because it is UI elements and cannot be set at the level

    In some products, Adobe as CC animate and animation character UI elements does not fit into their windows on a system here.
    For this reason many functions cannot be used, or the value, and therefore these packages are worthless and unusable on this machine.
    All and I really mean all other Windows programs work perfectly well, except these Adobe CC software.
    This bug is there to animate CC, but also in the new character animation software.

    I work on a laptop clean and very up-to-date with the latest drivers and 10 Windows installed.


    Watch the following snapshot to understand how irritating it is:
