Help!printing float values with two decimal places

hi there java pips! im a newbie to this technology so forgive me for this really stupid question....i would like to perform mathematical operations on two float values....the problem is i want to print them in a standard format and that is i want them to be displayed with two decimal places (e.g 190.00, 12,72, 1,000.01) how can i do this?

Try java.text.DecimalFormat
NumberFormat nf = new DecimalFormat("0.00");
System.out.println(nf.format(x));

  • Convert amount with four decimal places to amount with two decimal places

    Hi,
    for specific reasons we have set the prices to four decimal places. However, in an invoice the staff needs to see all prices with two decimal places. Therefore I have created new user-defined fields which should show the rounded values However, I have not yet found the right formatted search that outputs the value with two decimal places including currency symbol.
    The statement 
    SELECT $[$38.20.NUMBER]
    outputs the value with two decimal places which is fine, but it does not contain the currency.
    The statement
    SELECT $[$38.20.0]
    outputs both value and currency, but the value still has four decimal places as the original price.
    And the statement
    SELECT CAST($[$38.20.NUMBER] AS VARCHAR(20)) + $[$38.20.CURRENCY]
    outputs a value with even six decimal places.
    Did anyone already have the same problem???
    Or does anyone have any idea???
    Thanks and regards
    Corinna

    Hi again,
    the value should be displayed in a user-defined field of the screen.
    The result of the query
    SELECT $[$38.20.NUMBER]
    has already two decimal places, so that I do not need a round here. But the currency is missing.
    When I add the round function to the query
    SELECT $[$38.20.0]
    it does unfortunatly result in an error.
    Any ideas????
    Thanks so much in advance!

  • How can I limit a double value to two decimal place?

    How can I limit a double value to two decimal place?
    Java keeps on adding zero's to a simple double subtraction:
    1497 - 179.64 = 1317.3600000000001The answer must have been simply: 1317.36

    If the trouble is with output ...
    If the trouble is with value accuracy ...The trouble is with OPs understanding of and/or expectations of IEEE 754 floating point numbers. o_O
    [And it's probably a view (output) issue.]
    how can i actually use numberformat to cut those
    unwanted decimal places?Read the API - Puce already provided the link.

  • Uploading Number with Two Decimal Places

    I am trying to import data from my excel file to table in the database using SQL Developer.
    It is working fine except that in my excel file I have data with two decimal places, but during import it shows only one decimal place. Is there any way I can import data with two decimal places?

    This works well with SQL Dev 1.5.X.
    Guess it would have been a bug in prior versions.

  • How to take float precision to two decimal places?

    Hi, everybody:
    I'm a straight noob...first week in Java programming. Before you bash me for not checking FAQs and such, believe me, I have.
    I have tried BigDecimal movePointLeft, but I don't know how to construct it using proper syntax. I also tried currency and toString but I keep messing up my syntax somehow. Four hours into this and nothing is working.
    Here is the problem: I have a float. I want to format its output to two decimal places, trying to achieve in Java what C would produce as:
    printf("The amount you owe is $%.2f", fltAnyName);
    Any help would be appreciated.
    Thanks,
    Rob

    Sorry, guys. I have tried both recommendations and I can't get either to work. I'm getting a compile error pointing to the delineating period between the "out" and "printf" when I try the C-like code. I have 1.5, too. I know your advice is sound so I must be doing something wrong. Can you insert the code DecimalFormat code that will correct this problem where it needs to go? The packages below have been included becasue of all the different solutions I have attempted.

  • Problems of setting values% with 2 decimal places in any graphics. What sho

    Guys, I have the xcelsius 2008 and can not make it work chart with values % and 2 decimal places. Already set up everything that I know the spreadsheet and graphics.
    Someone knows what can I do?
    Thanks Anderson - Sao Paulo - Brazil.

    Hi Anderson,
    To get values in % and upto two decimal, follow the below steps:
    Go to Chart properties-> Appearences Tab-> Text tab.
    Select the "Vertical Axis Labels" and go to the Number format present below in the window.
    Change the format to "Percentage" and set decimal places to "2".
    This should work.
    Please revert incase you have any queries.

  • !!!! How to maintain the value with 2 decimal places !!!

    hi
    i have a double var and i need to maintain it with 2 decimal places only..
    thanks..

    What do you mean with you need to "maintain it" with 2 decimal places?
    Do you want to display the number with 2 decimal places? If so, have a look at the API documentation of java.text.DecimalFormat.
    double d = 3.14159265358979;
    NumberFormat f = new DecimalFormat("0.00");
    System.out.println(f.format(d));

  • Double value truncated to two decimal places without rounding the value.

    I want to truncate double value to two decimal places without doing the rounding of the value.
    Is there any method which can directly do the truncation.

    There's many ways to achieve this such as using
    BigDecimal's setScale method or type-casting. This is
    the way I like to do it:double d = -5.239;
    d = d > 0 ? Math.floor(d * 100) / 100.0 : Math.ceil(d
    * 100) / 100.0;
    Your division by 100 may cause an rounding error, because there are numbers which no finite binary representation. That's splitting hairs! I know ;-)

  • Rounding to two decimal places in BPC/NW

    Hello,
    I am dealing with the task to round values to two decimal places. I have found some discussions in BPC-MS where the statement ROUND should work in logic. Unfortunately I am not able to make it work in the NW version.
    Isn't there also a parameter in the appset or application administration which would cut the numbers only to two decimal places (this task would be also a possible solution for us).
    Thanks for any help

    Hello Pravin,
    the second import worked fine. I realized that the class has changed to ZCL_BPC_SL_ROUND.
    I debugged the class and noticed that the parameter it_cv is not filled at all. Therefore the program ends before starting the rounding procedure. Here is the part of the code:
    Take CV into account
      clear l_success.
      loop at it_cv into ls_cv.
        clear l_val_string.
        loop at ls_cv-member into l_member.
          if sy-tabix eq 1.
            l_val_string = l_member.
          else.
            concatenate l_val_string l_member into l_val_string separated by ','.
          endif.
        endloop.
        if l_val_string ne space.
          l_success = add_dim_restriction( i_param = l_val_string i_dimension = ls_cv-dimension i_clear = abap_true ).
          if l_success eq abap_false.
            concatenate 'Failed to successfully add Dimension' ls_cv-dimension into l_log_msg
            separated by space.
            cl_ujk_logger=>log( l_log_msg ).
            cl_ujk_logger=>log( 'Exiting Round Method' ).
            cl_ujk_logger=>empty_line(  ).
            raise exception type cx_uj_custom_logic
              exporting messages = et_message.
            exit.
          endif.
        endif.
      endloop.
      if l_success eq abap_false. exit. endif. - here the program exits and therefore doesn't do any rounding.
    If I comment this part the system rounds correctly but runs on all records in the cube which degrades performance a lot.
    Could you please advice further if it is possible to restrict the data region only to the submitted data?
    Best regards

  • Storeing values in floate data type upto two decimal places

    Hi
    I want a float type field in my table but want to store value up to two decimal places.
    so what syntax i need to follow plz suggest.
    thanks

    it is not possible to store with Number datatype. if you are using the data to sho report, then change its format (like 45 to 45.00). if you want to store 45.00 in database, then you have to modify the datatype for that column. for this follow the following path
    1. Add a column of datatype Varchar2.
    2. Copy all the value of your number field to it.
    3. Drop the old column.
    4. However make sure that if you have used that column somewhare in arithmetic calculation, the modify it and use to_number function to do arithmetic opration.
