Printing exactly 2 decimal places

I'm trying to print my double type variables to exactly 2 places. but numbers such as 3.00 and 124.00 keep printing as 3.0 and 124.0. Is there an easy way to force the printing to two decimal places on a primitive double type value without having to cast it to a Double object and playing around with NumberFormat and all that entails?
thanks much,
jh

darelln has exactly the right answer, except that you must do the thing you don't want to do. If it were me, I'd go with his example. It's less work and much cleaner.
import java.text.*;
public class DoubleTest {
static double[] numbers = {3000, 124.12, 123.122, 3.0, 124.0, 10.2, 12.14, 1234.55};
static final NumberFormat f = new DecimalFormat("#.00");
    public static void main(String [] args) {
        System.out.println("Goofy way!\n");
        for (int i=0 ; i<numbers.length ; i++) {
            printD(numbers);
System.out.println("\nRight way!\n");
for (int i=0 ; i<numbers.length ; i++) {
System.out.println(f.format(numbers[i]));
static void printD(double dbl) {
if (dbl % 10 == 0) {
System.out.println(dbl + "0");
} else {
String sdbl = "" + dbl;
String predot = sdbl.substring(0, sdbl.indexOf("."));
String atdot = sdbl.substring(sdbl.indexOf("."), sdbl.length());
String postdot = sdbl.substring(sdbl.indexOf(".") + 1, sdbl.length());
if (postdot.length() == 2) {
System.out.println(sdbl);
} else if (postdot.length() < 2) {
System.out.println(predot + "." + postdot.substring(0,1) + "0");
} else {
System.out.println(predot + "." + postdot.substring(0,2));
java DoubleTest
Goofy way!
3000.00
124.12
123.12
3.00
124.00
10.20
12.14
1234.55
Right way!
3000.00
124.12
123.12
3.00
124.00
10.20
12.14
1234.55
and the results are identical!

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));

PO print preview displays incorrect setting in decimal places

Dear Experts
Please help me on the following condition.
I have a problem in print preview of a PO. It displays the incorrect setting for decimal place in currency.
It shows USD 1.404,00 whereby the amount should be USD 1,404.00
This only happens to a certain vendor that is doing PO for the first time from that country
Example:
I'm creating a PO for vendor 123. Vendor 123 is located in country A. No PO has been created for any
vendor in country A before. When I saved my PO, in print preview, the decimal setting is not correct.
But when I'm creating another PO, for vendor 234. Vendor 234 is located in country B. There have been
several POs created for vendors in country B before. When I saved my PO, in print preview, the decimal
setting is correct.
Both vendor 123 and vendor 234 is using currency of USD.
Is there any other setting with the vendor master in regard with the currency decimal setting for each
country for the vendor? Or something that I've missed out?
Diagnosis:
I've checked with the user profiles->default-> decimal notation. It displays 1,234,567.89 correctly
I've also run OY04, but the decimal setting is correct.
Thank you
Regards
Syukri

this has nothing to do with print preview, it is just basic country setting (OY01) how a quantity and value is written on a PO to a vendor is country xyz.
German uses to comma to seperate decimals, while USA uses the point to seperate decimals
this would be the German version 1.404,00, and this the US version:: 1,404.00
so if an American sends a PO to a German vendor, then the document will show 1.404,00 so that the German can understand that he wants 1404. (and not 1000 times less)

Printing a double to accuracy of 2 decimal places

Hi,
I have a double value and I want to print it to an accuracy of 2 decimal places. Is there any way to do this. I tried using the DecimalFormat by
doing the following
String str = Double.toString(value);
DecimalFormat dec = new DecimalFormat(str);
dec.setMaximumFractionDigits(2);
String res = dec.toString();But this doesn't seem to work. I am using java 1.4.
Thanks

You can use DecimalFormat but like this:
        double value = 1.345678d;
        System.out.println(value);
        DecimalFormat dec = new DecimalFormat("0.00");
        String result = dec.format(value);
        System.out.println(result);Or you can use a BigDecimal where you can specify the most appropriate rounding method:
        BigDecimal bd = new BigDecimal(value);
        bd = bd.setScale(2, BigDecimal.ROUND_HALF_UP);
        System.out.println(bd.toString());HTH,
Christian

Print Scale Percentage - Can the percentage go more than 2 decimal places??

Hello All,
Illustrator CS6
I want to know if it is possible to get more than 2 decimal places in the Print Scale Percentage option box (as shown below)?
It seems to round to 2 and I would like to get at least 3 for better accuracy.
Any thoughts?
Thanks
Geoff

Not that I know of. If you need it to be more exact, resize the artboard and scale the content. It's an arguable point, anyway, given how your printer will translate/ rasterize the stuff. Even if there were more digits, the result after the halfftoning might not at all be any different...

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));

ALV output is 2 decimal places, but prints as 3

Hi,
In my current ABAP program, the output is shown as 2 decimals, using the following domain:
Data Type: QUAN
No. Characters: 13
Decimal Places: 2
Output length: 17
However, during unit testing, it was found that during printing, instead of printing it out as 2 decimals (ex. 12.00,) its printed out as 3 decimals (ex. 12.000.)
The same thing can be noticed when using Print preview. It starts at the editable fields and continues onward to others.
Why is this occurring and what can I do to fix this problem?
Points will be rewarded and all help will be greatly appreciated.
Thanks,
John

Hi
Check once again the attributes of that Qty field in Dataelement and domain
Because for all QUAN type fields it is always 3 DECIMAL places
you are saying it is 2
check it
All the qty fields in SAP with data type QUAN uses/prints 3 decimals
so check and see
like fields LFIMG.MENGE,FKIMG,KWMENG all fields with 3 decimals

Printing two decimal places from BigDecimal values

I am using BigDecimal to represent money values. My output needs to line up so that (with a non-proportional font) the decimal point and the two decimal places are in the same columns for each line. But when the dollar value has zero cents, or has a number of cents that is divisible by ten, it drops the trailing zeroes, and drops the decimal point if the decimal places are both zeroes. For example, I want to see "25.00" instead of "25" and "25.50" instead of "25.5". It doesn't seem to make any difference if I set the scale to 2. (I have resorted to getting the toString() of the BigDecimal and hacking the string before I display it, but surely there must be an easier way?)
      BigDecimal aaa = new BigDecimal("25");
      BigDecimal bbb = new BigDecimal("25.0");
      BigDecimal ccc = new BigDecimal("25.00");
      BigDecimal ddd = new BigDecimal("25.5");
      BigDecimal eee = new BigDecimal("25.50");
      BigDecimal fff = new BigDecimal("25.75");
      aaa.setScale(2);
      bbb.setScale(2);
      ccc.setScale(2);
      ddd.setScale(2);
      eee.setScale(2);
      fff.setScale(2);
      System.out.println("SCALE SET TO 2: ");
      System.out.println("aaa = " + aaa);
      System.out.println("bbb = " + bbb);
      System.out.println("ccc = " + ccc);
      System.out.println("ddd = " + ddd);
      System.out.println("eee = " + eee);
      System.out.println("fff = " + fff);produces this output:
SCALE SET TO 2:
aaa = 25
bbb = 25.0
ccc = 25.00
ddd = 25.5
eee = 25.50
fff = 25.75Thanks,
Martin

Thankyou Dr. Clap. This solved my problem - I added an LHS to the setScale statements:
      aaa = aaa.setScale(2);
      bbb = bbb.setScale(2);
      ccc = ccc.setScale(2);
      ddd = ddd.setScale(2);
      eee = eee.setScale(2);
      System.out.println("SCALE SET TO 2: ");
      System.out.println("aaa = " + aaa);
      System.out.println("bbb = " + bbb);
      System.out.println("ccc = " + ccc);
      System.out.println("ddd = " + ddd);
      System.out.println("eee = " + eee);produced:
SCALE SET TO 2:
aaa = 25.00
bbb = 25.00
ccc = 25.00
ddd = 25.50
eee = 25.50

Decimal places in Query generator

Hi All,
I am observing a weird behavior in Query generator's execution of a simple sql query. the query is :
Select 0.002834
now, in the general settings - display - amounts , I put the decimal value as 4 or 6, then only it prints 0.0028 or 0.002834.
else it prints 0.00 (if the decimal place is 2). it should ideally have nothing to do with the display of amount. any idea?
(the effect is shown only after you change the decimal display, update it and close and reopen the SAP application.
Thanks,
Binita
Edited by: Binita Joshi on Apr 12, 2010 4:03 PM

Hello Binita,
>I have tried converting it to numeric(19,4) and numeric(19,6) but still the result was same.
Check your decimal places settings in
\Administration\System Initialization\General Settings\Display tab
Check the following values:
- Units (For meaurement)
- Decimals in Query
Now let' s say,
- Unit set to 6 decimal places
- Decimals in Query set to 2
run the following query in query generator:
select cast(0.000245 as decimal(19,6))
result will be
0.00
run the same query as FMS on item master data in any measurement field (lenght)
select cast(0.000245 as decimal(19,6))
result will be
0.000245
Now set the - Decimals in Query set to 6 on \Administration\System Initialization\General Settings\Display tab
run the following query in query generator:
select cast(0.000245 as decimal(19,6))
result will be
0.000245
This is a normal habit of SAP B1 rounding engine / displaying engine.

Decimal places on forms

The decimal places in General Settings>Display is set to 6 for Amounts and Prices. They would like only 2 decimal places to acutally print on the SO and AR Invoice. How can we do this?

Hi Kathy,
You can add another formular field with round(Field_XXX,2) to display only two decimal places for any fields. Then hide the long decimal field.
Thanks,

Formatting currencies and decimal places

I'm currently using NumberFormat.getCurrencyInstance() to format numbers as currency. However, one problem I'm having is that I'd like values with no cents to be formatted with no decimal places, and any values with cents to be formatted with the usual 2 decimal places. For example:
17 would be formatted as $17
17.45 would be formatted as $17.45
17.4 would be formatted as $17.40
The last one is the tricky part--I've tried formatter.setMinimumFractionDigits(0), and this works great for the first two cases. But for the last case, the number gets formatted as $17.4.
Basically my problem is I want a number to be formatted with zero or two decimal places and nothing in between. Is there an easy way to do this?
Thanks in advance.

Otherwise you are likely to find that you are getting .00 due to errors from previous calculations. You are right. Adjusted it to Locale aware
import java.text.FieldPosition;
import java.text.NumberFormat;

    public static void main(String[] args) {
     NumberFormat nf = new SpecialCurrencyFormat(Locale.US);
     double[] values = { 10000, 1000, 100, 10, 1, 10.1, 10.01, 10.001,
          10.002, 10.003, 10.004, 10.005, 10.006, 10.007, 10.008, 10.009,

              + nf.parse(formatted));
     } catch (ParseException e) {
         e.printStackTrace();
}The value adjustedValue is needed since NumberFormat doesn't seem to round the value. It just breaks.

Rounding a quantity field to one decimal place. PLEASE URGENT

I have a quantity field with three decimal places. I have to print this field with only one decimal place. This is in a smartform.
suppose: qty = 45.678
I want it to be printed as 45.7
Thanks in advance.

Hi Riki,
I think you can use Function Module ROUND to round off the value...
REPORT ZTEST_SHAIL4 .
data: out type p decimals 1,
inp type f.
inp = '45.678'.
CALL FUNCTION 'ROUND'
EXPORTING
DECIMALS =
input = inp
SIGN = ' '
IMPORTING
OUTPUT = out
EXCEPTIONS
INPUT_INVALID = 1
OVERFLOW = 2
TYPE_INVALID = 3
OTHERS = 4
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
Now use the variable 'out' to display the rounded off value...
Regards,
SP.
