Rounding off to nearest decimal point

i have these values
35.2
35.3
35.4
35.5
35.7
35.8
35.9
36.0
i am looking for indexes closet 35.74 in my array. (which is index 4.)
i used the "round to nearest" function and it gave me 36.
which is index 7.
what other ways to get the right index?
Solved!
Go to Solution.

You will always have some difficulties with rounding to a specific number of digits after the decimal point because of the way numbers are represented in binary. When expressed in binary 0.1 is an infinitely repeating expression. Regardless of the display the internal representation of the number always uses the maximum resolution for the data type (8 bytes for DBL).
So you need to be very careful to define exactly what you want. If you have an array of values (regardless of the way they are displayed) Then you can find the closest to a Test Value by subtracting Test Value from the array and finding the minimum of the absolute values of the differences.
Note that in the image below the same values are in Array and Array 2 with the display on Array 2 set for 20 siginficant digits.

Round off to two decimal places

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.

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

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.)

Rounding off to 2 decimal places

Hi,
I use "Double" for my calculations and since I am working with $$ ;-) I need to round it off at 2 decimal places. Any quick way to do this? or do I have to write some major code for that?
Thanks

This works for all the test cases. Try this
import java.math.BigDecimal;
import java.text.DecimalFormat;
import java.text.NumberFormat;
class RoundOff {
     public static void main(String args[]) {
          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("173449.8"));
          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("173449.98"));
          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("-1.0"));
          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("-1.0"));
          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("-141.036"));
          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("-00.1"));
          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("-0.0"));

          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("173449.0.54"));
          //RARE EXCEPTIONS BUT WONT OCCUR
          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("0125."));
          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("0125.979.79E"));
          //RARE EXCEPTIONS BUT WONT OCCUR

          System.err.println(" FINAL OUT PUT >>> " + formatPrecision("173449.999"));
     private static String formatPrecision(String s) {
          if (s == null || s.trim().length() == 0) {
               return "0.00";

          int ind = s.indexOf('.');
          String dec = "";
          if (ind > 0) {
               dec = s.substring(ind);
               if (dec.length() == 1) {
                    s = s.concat("00");
                    return s;
               if (dec.length() == 2) {

Rounding off to nearest whole number without condition

hi,
i want to round a real number to an integer value,,wihout any conditions like
10.01 should be 11
10.1 should be 11 and like that
is it posible to do it?
thanks in advance.
amit

It doesn't look like you are trying to round to the nearest whole number here. It looks like you are trying to find the smallest integer value that is greater than or equal to the real number. If so, you would want to use the CEIL function (i.e.
1 SELECT CEIL(10.01)
2* FROM dual
SCOTT @ hp92 Local> /
CEIL(10.01)

Rounding off to nearest value with formatNumber

Can I use the formatNumber tag to round my numeric value to the nearest value?
Like if it's 15.7 I would like to display 16
And if it's 15.2, I would like to display 15
I could successfully truncate by giving a patteren but Im not sure if I can round it off.

Yes you can - the following works on JSTL 1.1 / Tomcat 5.5 :

Rounding off float to 2 decimal places and returning the float

I tried doing bigdecimal but it doesnt work. :
BigDecimal bd = new BigDecimal(5 * 0.0394);
          retval = bd.floatValue();
          System.out.printf(" th %f\n",retval);
I see 0.197000. I know that there are 6 places since I didnt do %.2f. However its not the printf thats important . The float I want to return must be rounded off to two decimal places.
Thanks in advance for the help,

How to round off quantity in inventory

Hi,
How to avoid decimal places for PC(Piece) in the goods movement transactions.. I have given 0 decimal places in CUNI transaction. It is working properly for Production Order during Conrimation but it is not working in Inventory transactions like MIGO, MB1C,MB1A....
for example When I enter Unint of entry In Alternate Unit say '10 KG' System Automatically Caliculates quantity in base unit in decimal places say 115.012 PC based on the conversion factor defined in material master.
My requiremet is the base unit quantity PC rounded off to nearest value in as 115 (PC).
The same thing is working fine for production order.
please suggest me how to do.
Thanks,
Shekar

this all depends on your conversion rate enterd in material master.
if 115.012 PC equals 10 KG.
what do you actually want the system to do,
it would now that you would get 115.012
you want it to be 115,
this would then mean that you have to modify the entered quantity from 10 to 9something
Is it that what oyu want?
you certainly cannot have 115 PC and 10 KG if you dont change the conversion rate in your material master

Working With Prices/Decimal Points

I've recently figured out how to perform calculations on values by assigning them to variables in a click function however I'm working with prices in my app and it seems difficult to get prices/decimal points to claculate properly. At the moment my app looks like this:-
<?xml version="1.0" encoding="utf-8"?>
<mx:Application

<mx:Script>

var addon2Float:Number = parseFloat(addon2.text);
var addon2Number:Number = new Number(addon2.text);

<mx:NumericStepper id="quantity"/>
<mx:Button label="Button" click="getTotal();"/>
<mx:Text id="total"/>
</mx:Application>
It works ok if the numbers in the text areas are whole numbers like 8 or 4 but if I use numbers like 02.99, 05.09 the result comes out a bit srange. For example the result of the numbers that I have in there now if I set the value to 2 in the numeric stepper is 61.900000000000006 when I know from using a real calculator it should be 61.9. Is there any way perhaps of rounding this code to the nearest decimal point so it appears as 61.90?
Are there any good tutorials that any of you know of when working with prices/decimal points in flex?

I've managed to find the solution for this - the currency formatter. If anyone's interested or has similar problems her's the code that solves it for me:-
