How check and rounding a whole number?

Newbie question:

How can I check a given integer (and not int) to see if there are round and next round.

for example
If the integer is 3456 - do nothing.

If the integer is 3456.9 - round until 3456

Thank you!

This is the behavior of the integers already. If you assign a number to floating point to integer (int or integer) it truncates the fraction part.

  • How I afford two fields and round?

    I need an average of two fields and then round the whole number closest. The two fields each will always have a value.

    If someone could help me out, I would appreciate it.

    T.

    Assuming you want it's a custom script calcuation for a field, it might look like this:

    Custom calculation script

    (function () {}

    Get the field values as numbers

    var v1 = + getField("text1").value;

    var v2 = + getField("text2").value;

    Set the value of this field to the average, rounded

    Event.Value = Math.floor ((v1 + v2) / 2);

    })();

    More information about the Math.floor method can be found in any decent JavaScript reference.

  • Round the percentage to a whole number

    Hello

    I'm still pretty new to perform calculations of script and thereby an individual seems a bit more complex for me.

    I am trying to determine the difference in percentage between 2 numbers and display the percentage as a whole number. Logically my calculation looks like

    (numericField1 - numericField2 / numericField1 * 100)
    (e.g. 1000-850 / 1000 * 100 = 15%)

    I need help with my math and especially round the % to an integer. I wouldn't have all of the answers posted as 22.66666%

    The code below is somethig I tried

    Event.Value = roundNumber ((this.getField (numericField1) .value - this.getField ("numericField2t") .value) / this.getField (numericField1) .value, 2) + "%";

    function roundNumber (num, dec) {}
    var result = Math.round(num*Math.pow(10,dec))/Math.pow(10,dec;)
    return the result;

    Any advice would be great!

    Adobe is actually this really simple for you.  If you use a numeric field to display the result, the display for the field template will control the way number.  You can set a percentage pattern:"num{zzzz9.99%}" to control how many digits will be displayed, and how many digits will be important beyond the decimal point.  If there is more than numbers, Adobe will automatically complement number.  In the attached example, I used the boss

    "{zzzz9 %} num" to ensure that only a whole number will be displayed.  Adobe uses the normal rounding rules: 0-4 rounds down, 5 to 9 rounds.

    In addition, the percentage will automatically multiply the value in the field by 100, so you don't need to do it in your script.

    For the attached example, I added your script FormCalc calculation to Calculate the result field event.  The script is now simply:

    (NumericField1 - NumericField2) / NumericField1

    Adobe takes care of the rest.

  • Recently switched from PC to Mac. I have the CD for the CS6 Adobe Creative Suite for Mac and PC. How can I get the serial number of the CD Mac OS with no disk drive?

    Recently, I switched from PC to Mac. On my PC, I got the Adobe Creative Suite Design & Web Premium (academic edition) CS6. I bought the product through my school and have two installation CD, for Windows and Mac.

    I try now to download this product on my new Macbook, but do not have a hard drive. When I check my saved items, it says that I have the Creative Suite CS6, but under the platform, he said "Winner" and serial number is for Windows product. Of course, this won't work for my Mac OS.

    So my question is, how do I get the serial number of the installation CD Mac OS with no disk drive? I guess that the numbers are different because when I put the Windows product number in the install window on my Mac, it does not work.

    So my question is, how do I get the serial number of the installation CD Mac OS with no disk drive?

  • How can I check and delete the corrupted files?

    I was told that my laptop performance could be carried out by missing or corrupt files. I can't find the system check in the Panel, and it is not found when I try to kick it and run. I don't have the original recovery or installation disk disk.

    According to the page I've linked in the other post: Hard Drive16 GB (Solid State Drive Flash Module).  Solid State Drive SSD =

    You can always do another:

    Check and repair corrupt files is to open cmd in the start menu, then right click "Run as Administrator".  Then type chkdsk c: / r

    • If you get an error "Chkdsk cannot run", type in, ChkDsk runs on your next Windows startup

    Who will eventually fix any corrupt system files, but not others.  You suspect corruption in the other or all of the files, then probably the SSD is having problems.  That can be fixed with conventional methods, as far as I KNOW.  Maybe time to replace it with a new SSD or hard drive classic, if possible.  Don't know how HP implimented the SSD in the mini.

    Since there is no DVD/CD drive integrated into the unit, get an external hard drive or USB key and backs up all data that you consider important before things get worse.  You can buy 16 GB flash drives or bigger, so that would be my suggestion.  Just copy everything on a flashdrive before anything else is done.

    BTW: I found a recovery here media: http://www.computersurgeons.com/SearchProducts.aspx?sbt=hp%20mini%201030nr%20&bkm=Results#Results

  • How to set the 1st online number = 10 and increment 10 whenever you press the button to add a new line. Also enable users to enter the generic numbers, IE 13 and still increment of 10 23 or whatever.

    How to set the 1st online number = 10 and increment 10 whenever you press the button to add a new line. Also enable users to enter the generic numbers, IE 13 and still increment of 10 23 or whatever.

    I already have my chart updated in place with a button that will add new lines when pressed.

    Now, I want to clarify that the 1st row is 10 and all the other rows after this increase by 10. It will also allow users to enter any number they want, and the next line will increment of 10.

    Help please.

    Try changing the line button Add the following JavaScript code

    newRow var = Table1._Row1.addInstance)

    If (newRow.index > 0)

    {

    newRow.NumericField1.rawValue = newRow.resolveNode ('Row1 [-1].) NumericField1') .rawValue + 10;

    }

    You need to change this code to match your name on the form, but basically the method addInstance() returns the new row, the newRow.resolveNode ("Row1 [-1]... will get the value of the previous row and then add 10.
