Rounding off double

how do you round off a double to the nearest hundredth place?

You can't because a double is typically not capable of representing an exact 100th place.

  • Round off Double to 2 decimal places??

    Hi all the pro out there..
    anybody can tell me how to go about rounding off eg 5.9542 to 2 decimal places in java? i went to search in API Double class, no method that allow me to do that..
    is there any other way?
    pls advise thank you

    If the former, you can do it manually by multiplying by an appropriate number, casting to int, and then dividing by the same number.Although this won't always work.
    Suppose you want 1.125 --> 1.1
    1.125 --> 11.25 --> 11 --> 1.1 plus some epsilon, since 1.1 can't be represented exactly in base-2.Yes, I know that (I assume you knew I knew that). So, maybe the OP needs to use both methods in combination (and maybe use some rounding method [such as in the Math class] other than cast).

  • How to avoid rounding off large Double values?

    For converting from String to Double, consider a piece of code as below:
    String str = "999999999999999.99999";
    Double d = Double.valueOf( str );In this case, d will contain the value 1E15 and not 999999999999999.99999.
    Is there any way by which we can avoid this rounding off?
    TIA,
    Ninad.

    > String str = "999999999999999.99999";Note that you have a total of 20 decimal digits here.
    A double only has 53 bits to represent the mantissa
    so it can only accurately represent about 16 decimal digits.

  • Float, AUTO ROUNDS OFF

    float a = 9999999.9f
    System.out.println(String.valueOf(a));
    (i.e., when the number of digits on left of decimal > 6)
    gives a rounded off result as:
    1.0E7
    HOW CAN WE AVOID ROUNDING OFF,
    & retaining the standard notation(not scientific)

    the problem:
    Any idea on auto ROUNDING OFF
    is the number of SIGNIFICANT DIGITS in float
    restricted to 8?Float numbers ARE automatically rounded off. But the rounding takes place in the binary representation, not the decimal representation. If you want to control rounding of decimal numbers, then use a BigDecimal object. It lets you control rounding in several different ways. And the accuracy of a float number is about 7 or 8 digits in decimal, yes. If you use double numbers, you will get significantly better accuracy.
    would it help if I tried a JVM diff from SUN
    as Jikes???No. Java is standardized. You should get the same results from all JVMs.

  • Reading data from force gauge rounding off decimals

    Hello everyone.  I am new to Labview and this is my first posting on the forum.  I am currently writing a program to record pull tests on crimps using a force gauge.  Everything is going fairly well for it being my first project except when the data I am reading from the force gauge is rounding off the decimals.  I am sure it is where I am using the absolute value and conversion functions but I am unsure the correct way I should be doing this.  Thanks in advance for any advice.  Also, I tried searching on this but did not come up with anything so I apologize if this is a redundant topic. 

    The reason you are losing your decimals is because of the data type you are using.
    If you notice, your indicator is blue, indicating it is "I8" (an 8-bit integer).
    Since it is an integer, by definitiion it has no decimal precision.
    After you read in the data string, try converting it to SGL (single precision float, 32-bit) or DBL (double precision float, 64-bit)

  • CO assignment missing at at the time rounding off material in MIRO

    Dear All,
                  Iam facing the problem with co object assignment missing at the time of MIRO,
    >when iam posting miro with higher value than PO, it should hit rounding off of material(GL)
    >it is hitting that, but it is not allowing to post into the rounding off gl, showing error like cos object missing.
    >Here we r mapped setting in OKB9 with cost centers depends upon plant wise.
    >if i assign in okb9 valuation area mandatory level(1), it is not allowing me to post,
    >but if i assigh GL at main screen in okb9, instead of selecting valuation area mandatory(1),it is allowing me.
    Please help me how to overcome the problem, is there any special setting or logic for rounding off material gl.
    >That GL has cost element, cost center is in active,field staus group setting also correct,
    Where else i have to check please guide me.
    Thank,
    chinni

    HI,
    Once you set valuation area is mandatory, then you need to do another setting in the same screen.
    Select level 1 in the OKB9 initial screeen and double click on the second screen with header " Detail per business area and valuation area". There u need to enter the value with the combination of cost center and valuation area.
    You will not have any issue once you do this setting.

  • Rounding off a float to two decimal places

    I want to make a function where I shall pass a float and and integer.
    The float shall have to be rounded off to a value in the integer.
    Can anyone please suggest how to round off a float.
    E.g.: if the float is 12.56890 and I want to round it off to 2 decimal places, then it should be 12.57.
    Regards
    Hawker

    I didn't mention any datatypes like float, double.True, but that is what the question is about, so you weren't answering the question. For a change.
    As I mentioned, that was just a mathematical steps to round of the floating point value. (Not in any programming languages point of view).False. You didn't mention that at all.
    This is the code for that in java.So here you are mentioning datatypes and floats for the same piece of mathematics that you have already been told, with reasons, doesn't work in floating point.
    which seems to be working fine
    Seems to. What evidence do you have that the float actually got rounded? As opposed to got displayed as rounded? Which is not what the OP asked for.
    And of course all that code seems to do is round 0.01 to two decimal places, which again is not what the OP asked for.
    For any remaining fans of this 'technique', please explain the behaviour of the following code:
         public static void     main(String[] args)
              int     count = 0, errors = 0;
              for (double x = 0.0; x < 1; x += 0.0001)
                   count++;
                   double     d = x;
                   int     scale = 2;
                   double     factor = Math.pow(10, scale);
                   d = Math.round(d*factor)/factor;
                   if ((d % 0.01) != 0.0) // if 'd' really has been rounded this should be zero
                        System.out.println(d % 0.01);
                        errors++;
              System.out.println(count+" trials "+errors+" errors");
         }

  • Rounding off to two decimal places

    Hello,
    For simplicity, is there a method which will round off
    a double variable to two decimal places.
    Excample: if I have a result which equals 2.1999998
    and I want to display this as 2.20 in a TexTField.
    Any help would be much appreciated.
    Thanks

    If you are trying to do dollars and cents, I further recommend you use:NumberFormat currencyFormatter = NumberFormat.getCurrencyInstance();
    String currencyOut = currencyFormatter.format(yourNumber);to format your numbers as they will give the correct precision for international currencies simply by setting the locale, and they will also automatically handle the currency symbols ($, DM FR, etc.)

  • Need help with a round off.

    Hiya.
    I'm trying to get a little program to work (schoolwork I admit) but the end result is a little different then what I need it to be (and not asking for spoons here please).
    I'm trying to get the end result like xx.x but for the moment it ends up with several more digits (like xx.xxxxxxxxxxxx).
    Since I want it to round off like it should (second digit) <5 down to number below and >5 to number above, is there any way to stop a double on two digits?
    I'm using notepad and JDK and not allowed to use predefined methods (for a good reason I assume :P)

    i hope this helps....
    i just discovered it a few hours ago.
    if your input is double like
    double <name>=<value>;
    you can assign another variable which will convert it to int
    int d=(int)i;
    i hope it helps...=)

  • Rounding off Serv Tax

    D/ Friends,
    We want that Service Tax (including ECess & SE Cess on Serv Tax) shd be rounded off in PO. How is this possible? Any routine is required to be assigned to the Service Tax or thru something else? Weu2019re using TAXINJ.
    Pls advice.
    Thank you.

    Hi
    Go the T code OBQ1 select the appropriate condition type & double click, for which you want to maintain rounding value. Go to Group condition
    Select round difference
    Indicator that controls whether rounding difference is settled for group
    Conditions with a group key routine.
    If the indicator is set, the system compares the condition value at Header level with the total of the condition values at item level. The difference is then added to the largest item. So it will rounded off to the nearest value of condition

  • Csv round off error

    I am getting all the values under the channel "calc G level" in the attached csv file as round off value when loaded in Table view in diadem.
    Kindly help to solve this issue.
    Solved!
    Go to Solution.
    Attachments:
    bHard Brake.csv ‏54 KB

    The CSV loader tries to guess the datatype of you column. So in your case it looks at the first lines and guesses int.
    in newer DIAdem versions this was changed to guess double instead of int.
    For DIadem 11.1 dataplugin ight be a solution.
    If you have a lot of those files you can use a dataplugin to access them. In them you can switch the channel type to double and it would work out. If I remember right 11.1 already had the dataplugin wizard that makes generating dataplugins easy.
    Hope this helps a little

  • Rounding off the decimal place.

    how to round off to 2 decimal place for this following programs:

  • Rounding a double

    Hi,
    What's the best (and fastest since I got lots of values) way to perform a rounding on a double value?
    I think what I'd like to do is half-up rounding, so when it should round up to 2 digits e.g., it should cut off the rest when the third position is a 0;1;2;3 or 4 and should add one to the second digit, when the third is one out of them: 5;6;7;8;9.
    I tried it myself this way. Now this has happened - at the end (converting int to double) it screws at some values - why and how can I fix that or what is a better way to do this, since this solution looks kind of goofy to me?
        public double roundValue( double dTemp, int iDigits){
             // splitting up into the pure int part of the NOT rounded value
             System.out.println("****   dTemp to round: " + dTemp);
             System.out.println("iDigits to round to: " + iDigits);
              int iIntPart = (int) dTemp;
              dTemp -= (double) iIntPart;
              System.out.println("iIntPart: " + iIntPart);
              System.out.println("dTemp - only minor digits: " + dTemp);
              // calculation of a factor for the lower digits
              double dDigits = 1.0;
              for(int cnt = 0; cnt < iDigits; ++cnt)
                  dDigits *= 10.0;
              System.out.println("dDigits: " + dDigits);
              System.out.println("dTemp * dDigits: " + (dTemp * dDigits));
              System.out.println("Math.round: " + Math.round(dTemp * dDigits));
              System.out.println("Math.round/dDigits: " + ((Math.round(dTemp * dDigits)) / dDigits));
              // processing Math.round()
              dTemp = (Math.round(dTemp * dDigits)) / dDigits;
              System.out.println("dTemp - after: " + dTemp);
              // dTemp is now rounded
              dTemp += (double) iIntPart;
              /* here sometimes, the value returns results like this - why?
               * 4.941519877284079 -> iDigits == 2 -> 4.9399999999999995
               * 5.94004582533272 -> iDigits == 2 -> 5.9399999999999995
              System.out.println("****   dTemp after adding the int part: " + dTemp);
              return dTemp;
        }

    Thanx I tried it out and I thought I had to use Math.round() the way I did. But still what happens at the conversion from an int to a double - just curious?
    I did it now this way - I thought Math.round has some probs, with the digits in front of the point:
        public double roundValue(double iValue, int iDecimalPlace) {
            double dPowerOfTen = 1;
            while (iDecimalPlace-- > 0){
               dPowerOfTen *= 10.0;
            return (Math.round(iValue * dPowerOfTen) / dPowerOfTen);
         }

  • Issue in MODVAT Clearing Account and Rounding off of Excise.

    I have one issue in MODVAT Clearing Account and Rounding off of Excise.
    Example:
    Material cost    100Rs.
    Excise  value
    1. BED             10.5 Rs
    2. ECes             2.1 Rs
    3. HEces          1.3.Rs
    At the time of GR
    Material Ac Dr          100 
         To GR/IR                        100
    At the time of Excise Capture
    We done the rounding of Excise value
    RG23 A  BED         11
    RG23 A  Eces          2
    RG23 A  HEces        1
       To MODVAT            14
    At the time of IR . System create IR with reference of PO
    GR/IR  DR      100
    MODVAT         13.9
        To Vendor         113.9
    So here you can see that there is a difference of 0.1 in MODVAT account and hence we are crediting Vendor  with the lesser amount here with 0.1 RS.
    So we cannot reconcile the MODVAT Account
    Less Payment to vendor by 0.1 Rs
    So is there any solutions on that.

  • MIRO- excise and VAT duties Rounding off

    Hi all,
    A PO will have 20 items. Those 10 items will have excise duties and VAT amount. At the time of PO these excise duties and the VAT amount should not get rounded off. But while the user is doing MIRO, the value of these excise duties and the VAT amount should come to the screen as rounded off. Is it possible? If yes please suggest me.
