To the number of decimal places control user input

Hey everybody,

I am all new to LabVIEW and just learn how it works. I was wondering if there was a way to allow user input to change the number of decimal places (the output of my function is infinitely extensible).

I tried, but it did not work:

Using a digital input, I appended a string with "%" + '[INPUT]' + 'f' with the number of function concat strings and string functions. I used the resulting string as the formatting string in the value format function.

This doesn't quite work. The output should be something like "28.274", but instead, it displays "283f. Anyone know why? Is there a better way to do it?

In addition, attach a picture of the front panel and diagram of block for clarity.

(Yes, it's homework, but the assignment does not include allowing the user to adjust the number of decimal places, it's just something I would like to add.)

Get rid of the number 2 for the width of your decimal string number.  It requires a space before a number to a number.  %. 6F is not equal to % .6f.  The string format don't quite understand the first format string.

(PS.  It helps if you attach your VI.  In this way we can play with what you have rather than trying to recreate it from scratch.)

  • Change the number of decimal places according to the value of the field

    Hello world

    I'm doing a form using Adobe Acrobat.

    I want a field that usually has only 2 decimal places, to have 4 decimal positions ONLY when necessary.

    Example: If the value of the field is 3.53 that's fine, but if the value is 3,5346 I want to show him this.

    I played around field properties and I realized that I need to use a custom format script. I don't know where to start, however. Can you point me in the right direction?

    Thank you in advance.

    I just threw together quickly and did not test, take is as a general guide. It is intended to be placed in a JavaScript to the document level and called from custom Format script of the field. You can not put it simply everything as the script to Format because of the way that Acrobat behaves when you do.

    The point of the script is to calculate the number to use as the first parameter to the AFNumberFormant function, which is that Acrobat uses when configuring a digital format. I couldn't think of a clever name for the function, so I leave it to you:

    function fmt1() {
    
        // Set the minimum number of digits to the right of the decimal
        var min = 2;
    
        // Get the field value, as a string
        var val = event.value;
    
        // Round to the nearest 10-thousand of a cent
        var rn = util.printf("%.4f", val);
    
        // Replace any trailing zeroes with nothing
        rn = rn.replace(/[0]+$/, "");
    
        // Get the number of characters after the decimal
        var num = rn.split(".")[1].length;
    
        // Set to the minimum if appropriate
        if (num < 2) num = 2;
    
        // Use built-in formatting function
        AFNumber_Format(num, 2, 0, 0, "\u20ac", true);
    
    }
    

    Call it like that in the case of the field Format:

    fmt1();
    

    If this isn't a calculated field, but the one who interacts with a user, you'll want to add a function with the swing, something like:

    function keystroke1() {
    
        AFNumber_Keystroke(2, 2, 0, 0, "\u20ac", true);
    
    }

  • Number of decimal places in the recorded data

    Hello world

    I use the writing on measurement file Express VI and everything works well except for one thing. I have too many decimal places in my saved data. I really need 2 decimal places for my application. Is there a way I can fix this without having to open the file with Excel and format numbers?

    Just FYI I'm writing dynamic data, the VI write is configured for text (.lvm) file format, and it is delimited by tabs.

    Joint are two images: one of the worksheet of stored data, and the other is my writing to measure Express VI.

  • How to round a number to a specific value and not to a certain number of decimal places

    Hello

    I'd round up the numbers according to a grid.

    Let's say I have a grid of 6 between 3 and 4 (3.0 3.2 3.4 3.6 3.8 4.0)

    I'd round up to the nearest number in the grid, so if I choose 3.7125, it will turn to 3.8.

    I found already in the forum how to round decimal degree, but not in my approach.

    You know to force rounding to the nearest of the grid.

    I thought a ramp up to make the grid then interpolate the number and use its index to round. But I don't know that there is a much easier way.

    Thank you

    Zied

    These ideas, everything seems to work if you try to round up to a set of specific values.  But you must set specific values for all the possibilities.

    If you want to round to a given interval, there is an easier way to do it.

    If you want to round each 0.2.  Divide your number of this interval.  Round to the nearest integer.  Multiply your number of this interval.

    If you need to force a number less than or greater than a given to be in this range, such as having range 1.255 round up to 3, then put a stove and Coerce before or after this piece of code.

  • Number of decimal places in Write Back

    Hi all

    We use the writeback option ERPi/FDMEE to rewrite data in Oracle EBS12. Everything works correctly, but when extracting data from Hyperion FDMEE takes data in 7-8 decimal places. Is it possible for this round to 2 decimal places when exporting data?

    What version of FDMEE?

    When the data is written back to the LES, it is actually extracted using a view.

    For EBS, there is a view named AIF_EBS_GL_INTERFACE_V, where you can find the SQL code to extract data from FDMEE

    You can try to change this view to include a ROUND for the column amount:

    CREATE OR REPLACE VIEW "FDMEE" OF THE FORCE. "" AIF_EBS_GL_INTERFACE_V "("SEGMENT1","SEGMENT2","SEGMENT3", 'SEGMENT4', 'SEGMENT5', 'SEGMENT6', 'SEGMENT7', 'SEGMENT8', 'SEGMENT9', 'SEGMENT10', 'DIRECTION11', 'SEGMENT12', 'SEGMENT13', 'SEGMENT14', 'SEGMENT15', 'SEGMENT16', 'SEGMENT17', 'SEGMENT18', 'SEGMENT19', 'SEGMENT20', 'SEGMENT21', 'SEGMENT22', 'SEGMENT23', 'SEGMENT24', 'SEGMENT25', 'SEGMENT26', 'SEGMENT27', 'SEGMENT28', 'SEGMENT29', 'SEGMENT30', 'QUANTITY', 'ACCOUNTING_DATE', 'CURRENCY',"LOADID","ACCOUNT_TYPE") AS

  • How can I limit the number of rows in a text input field?

    I don't want to have it scrolling. For example If the field has four lines the user is writing the fourth lineand give such ENTER or continue type up to are no longer on this line, I don't want to create in the fifth line text field. Il a do?

    An approach here is to limit the number of lines, someone else might have a different approach... "tf" is the name of the instance of the textfield object.

    tf.addEventListener (Event.CHANGE, checkNumLines);

    function checkNumLines(evt:Event):void {}
    If (TF.numLines > 4) {/ / deletion of the last typed character}

I have now, I can compare the current values with the values from the previous loop pass, but this isn't an option.

    I'm looking for some kind of property as active control node or something similar.

    It does not exist.  You can create your own time stamp control (like an XControl), or you can simply watch to see if the window is displayed. You can do the last using VI server functions or you can use the API of the operating system. For Windows, you can use the LabVIEW Windows utilities library.

    Hi all

    you have a problem with 'Find '.

    So I take the Arith. Average of 30 blocks

    zaeler1         =  zaeler1 + 1

    Thank you

    Hi Michael,

    Brad is right that it is difficult to debug the convoluted formulas, but I would give it a try

    intmyresult    =  find ("Ch (" "[" & ChannelNr & "" "] / I_" example & "\15" "" ") ' >" & (arithmean) & "", morefail ")

    I guess you're in DIAdem SCRIPT and not in the calculator? If so, I think that your conversion of 'arithmean' is incorrect (in case you have a German localization of Windows):

    What happens if you write? :

    Call Msgbox (arithmean)

    For me, the result is:

    1 415' comma!

    Is it the same for you too?

    If so, your channel has an extra comma and is misinterpreted by FIND.

    Please try to write:

    Str (arithmean)

    Instead of

    (arithmean)

    I hope that helps you along!

    Best regards

    If I delete the reference to the firstRowContainer it also delete the page layout, button and also the textArea and free the memory?

    Yes, "delete firstRowContainer" deletes everything.

    I usually format this way so the hierarchy is obvious:

    Button *locationButton;
    TextArea *locationTextArea;
    
    Container *firstRowContainer = Container::create()
      .layout(StackLayout::create()

  • Change the number of digits after the decimal point

    Hello

    We have created a report from ALS and the ALS very basic dashboard for customer agreeing the format of a table containing:

    Name of service SLA percentage

    blah blah 100%

    In order to display SLA percentage for the period concerned, we used the baselineAvailability/period/average metric.  With the 'normal' rendering engine, this displays the integers:

    However, as he is a figure of ALS, we report to two decimal places.  If we use the "raw" rendering engine, we get three decimal places - but no percentage symbol:

    Is it possible [easy] to choose the number of decimal places for a measure in a table?  Otherwise, is that you can add a text of token / custom field?

    Thank you

  • Disable the number of items based on the values of another page/table

    Hi people,

    I have a form with 15 fields such as:

    Form1

    id_plan = 1

    level 1 = 2

    level 2 = 2

    level 3 = null

    level 4 = null

    level 5 = null

    level 6 = null

    and so on...

    Later, in another form that I have:

    Form2

    ID

    id_plan (from 'form1')

    account: 10.01 (based on the number of decimal places defined on the level of 'form1')

    So, I need to disable page Form1 items if I had some values of Form2. But only the levels where the account is registered. In the example above, only level 3, level 4, level 5, level 6 and so on would be activated.

    Any suggestion?

    I could put a read only condition for any page in question, is it good? or there is another suggestion?

    Thank you

    bsalvador

    Hi people,

    To resolve my issue, I used the read only option. I chose the body of the PL/SQL function returning a Boolean and put

    Start

    If (CST_RETURN_LEVEL(:P7_ID_PAR_PLANO_GER) > = 2) then

    Returns true;

    end if;

    end;

    where CST_RETURN_LEVEL is a function that returns the last filled level. If the point of the page is at level 2, I test, if CST_RETURN_LEVEL(:P7_ID_PAR_PLANO_GER) > = 2 then I returned true for read only and so on for other page elements.

    Thank you

  • Result of the calculation were separated to the whole and decimal, number not rounding correctly

    I have 2 fields as a result of sharing: the whole and decimal number (1 decimal place). I Math.floor the result to get the whole number and everything is fine until I hit a case where the result is 92,97.

    This should give "93" in the whole of the field and '0' in the decimal field, instead it gives me '92' and '10' (even though I'm only hosting 1 character in the field).

    How can I get the '93' and '0' in the following code?

    fieldLVEDV = this.getField("LVEDV").value;

    fieldBSA = this.getField("BSA").value;

    If (fieldLVEDV! = "" & & fieldBSA! = "") {}

    totalLVEDV = this.getField("LVEDV").value + ((this.getField("LVEDVDec").value)/10);

    calculation = (totalLVEDV / fieldBSA);

    calculationDecimal = calculation;

    partWhole = Math.floor (calculation);

    if(partWhole <0) {partWhole =' ' ;}}

    this.getField("Index").value = partWhole;

    this.getField("IndexDecimal").value = Math.round (10 *(calculationDecimal-partWhole));

    {If (this.getField("IndexDecimal").value = '10')

    {

    this.getField("Index").value = partWhole + 1;

    this.getField("IndexDecimal").value = "0".

    }}

    } else {}

    this.getField("Index").value = "";

    this.getField("IndexDecimal").value = "";

    }

    I thought I'd add the blue part would do the job, but obviously it did not work.

    Ah, your problem is that you do not use the correct comparison operator. To check if two values are equal, the operator is "==" not not "=". Using "=", you assign the value 10 to the field which you then pass in 0 a few lines down. Use 'is' and things should work correctly.
