Rounding Doubles to Two Decimal Places

Hi All,
I've searched the archive and found a few different
posts regarding restricting the number of decimal
places in doubles. However they all suggest different
methods, BigDecimal, NumberFormat etc.
Which is the simplest method of rounding a number say
10.023445656 to 10.02?
I tried using the java.text.NumberFormat but this
turns the double into a string and I need the end
result to be a double.
ThanksI ahve a small code that can do the work for u:
import java.text.*;
double format(double val, int dec){
    double multiple=Math.pow(10,dec);
    val=Math.round(val*multiple)/multiple;
    DecimalFormat df=new DecimalFormat("0.00");
    String format=df.format(val);
   double dval=Double.parseDouble(format);
   return dval;
}//end of functionHope that helps!

Price per unit is getting round off to two decimal places.

Hi Gurus,
In the Billing output, the Price per unit is getting round off to two decimal places.
How can we avoid this or allow 4 decimal places for such cases.
In the same pricing procedure, we have two pricing condition types PR02 and ZR01.
When PR02 is being used,it doesnt rounds off Price per unit.e.g .578888 = .578888
But when ZR01 is being used the system rounds off price per unit.e.g.578888 = .58
Please suggest where is the setting for it.
Thanks

Hi,
Which currency you are using? If its INR, then it will do only for 2 decimal places.
The solution for ur problem can be ractified by changing the scales :

How do I round calculations to two decimal places (form-wide)

Hi,
I've created an order form where customers input the quantity of product they want to order and the form outputs the total due (including shipping and sales tax). Depending on user input, the resulting total sometimes contains more than two decimal places. How do I round calculations to two decimal places? Is there a way to do this form-wide?
I'm new at using Acrobat for calculations. Any help would be greatly appreciated! Thanks...

The above will affect the displayed value not the actual value of the field nor its value when accessed in another computation. This behavior may cause an error of 1 cent or more in the grand total or sales tax computation. If you want the the value and displayed value to be the same value you can use the following Validation script:
event.value = util.scand("%,1 0.2f", event.value);

Round off to two decimal places

hi
i have a filed in it values are there i want to round off to two decimal places
which is the function module for it please suggest
regards

Hi Nishant Arora,
Please check this code.
DATA: N1 TYPE P DECIMALS 4 VALUE '0.0565',
N2 TYPE P DECIMALS 2.
MOVE N1 TO N2.
WRITE: N2.
Here the value is get rounded to 0.06.
Rather than function modules you go with this. I think it is easier.
Reward points if useful.

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.)

Print Doubles to two decimal places?

When I do calculations on my double numbers and then print them on screen I get a string of digits after the decimal point. Can anyone give me the code as to how I use the DecimalFormat class to make these digits print to 2 decimal places. I am sure it is very simple line or two of code but I am unsure how.
Thanks

double number = 123456.789;
DecimalFormat df = new DecimalFormat("#,##0.00");
System.out.println(df.format(number));

Convert rounded number into two decimal places

Hi All,
I have a Number 156 stired in a column having number(10,2);
but i want to update it into 156.00......
May be simple,,,,but how?
Edited by: 887268 on May 29, 2012 10:04 AM

Hi,
156
156.00
156.0000000000000 and
00000156.0000 are all the same NUMBER. There's nothing to convert.
If you want to display a NUMBER in a certain way (e.g., with 2 digits after the decimal point) then use TO_CHAR, or have your front end format the column. In SQL*Plus, for example, you can use the COLUMN command:
COLUMN   sal     FORMAT 99999.99
SELECT ename
,       sal
FROM    scott.emp
;Output:
ENAME            SAL
SMITH         800.00
ALLEN        1600.00
WARD         1250.00
JONES        2975.00

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
Jan

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 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");
     }

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.

Somebody please help me.
thanks

hi,

Round to two decimal places...and keeping trailing 0

Ok, I have done a search on rounding. So I made this function:
    private double round(double number){
       double d = Math.pow(10, 2);
       return Math.round(number * d) / d;
    }However, if I use a number like 3.59999, it returns 3.6. For what I am using it for, I need it to return 3.60. Any ideas? Thanks.

You normally only format for display! You seem to be wanting the default format to show 2 decimal places. This makes no sense. Internally a number(double or float) doesn't know about decimal places so how can the default format know you want 2 decimal places?
For the most part you only need to worry about decimal places when you print a number using the DecimalFormat class.
There are times when you might want to round values to 2 decimal places before doing more calculation. I have only met this when adding monetary values when it is important that a column total equals the sum of a displayed column values. In this case one uses something like the technique you originally proposed to round values before summing them. You then use DecimalFormat to display the values.
