Floating Decimal problem!!
Dear all,
Dear all,
I wrote a java application to manipulate some data format transferring. I can run it on Windows with jdk 1.3. But when I ran it on Red Hat, I got such problem:
Exception in thread "main" java.lang.NumberFormatException: -0.715
at java.lang.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1213)
at java.lang.Double.valueOf(Double.java:183)
at java.lang.Double.<init>(Double.java:258)
at MethodEvaluation.ReadDataIn(MethodEvaluation.java:259)
at MethodEvaluation.RunLCV(MethodEvaluation.java:67)
at MethodEvaluation.main(MethodEvaluation.java:29)
I'm very confused! Why the same program and the same data set got different results !?
Please help me to resolve this problem! Thank you!
It might have to do with locale settings and the decimal delimiter's being . or ,

I have this floating keyboard problem. Is there a fix to this?
I jail broke my device and I know it's not anything I downloaded after that because none of the things I downloaded have anything to do with mail or photos. This only happens when I try to send a photo through email. Help please!

My site passed the Browser compatibility check in DWCS3, however, after launching site online and viewing it on a IE6 PC computer, the home page does not display correctly: the center section drops down. I checked for a potential float drop problem by adding up my widths including margins and padding: Sidebar left is 170 px, main content area is 370 px (this is the area that drops), sidebar right is 180 px = 720 px. The container is 780 width so I don't understand why the center doesn't fit but drops down because there seems to be 60 px left in the overall width to provide plenty of room. The main content area doesn't have a width specified, just a left and right margins (left set at 170 and right set at 180). I didn't try a conditional comment because I am not that familiar with coding. Any suggestions would be helpful. Also, don't understand why this wasn't flagged in the DWCS3 Browser compatibility check when it scanned for IE6. The address is http://www.eastontroop66.org and it's the home page. Thank you!

"Floating ownership" problem on eSATA DS4600
I have a Promise DS4600 unit that is hooked up with eSATA. Previously, I used System Preferences to move some user account home directories to this unit since some of them are just gigantic. It's worked great... until...
...somehow, this volume has acquired the "floating ownership" problem. The floating ownership problem is where the system shows the currently-logged on user as the owner of every file and directory inside the volume even though "ignore ownership on this volume" has been disabled for quite some time.
Does anyone have any idea how this happened or how to fix it? I'm trying to avoid a data move/permissions rework because the amount of data is huge (3 terabytes or so) and it would be difficult. I have a feeling there is a setting stuck, but I cannot find any data on it. I know there is a post about this issue on the SuperDuper! blog, but there is no information on how to fix it. They just talk about how they worked around the issue on their application.I have a Promise DS4600 unit that is hooked up with eSATA.

Float type problem helppppppppp
I have a jsp page, which retrieves values from a html page, my problem is that
i can insert the values in database, but the problem is that it does not insert the flot type values...

it does not shows in float type.

Hello experts.
I have a problem with decimal on a query that its used in a VDT.
In the dev system it works fine, but when I transport it to Prod system, the decimals doesn't represent fine.
An example:
dev system prod system
2,50 UN 3 UN
Does anyone help me on this.
Thks
Vitor Ramalhohi,
If you are not getting the decimal values let us say 2,50 instead of 2.50 then what you need to do is go to your user profile in production and select defaults tab and select the required decimal notation. The report should now show the values 2, 50 as 2.50.
Hope it helps......... -
Ok to give a background to why i am writing this and so everyone has a better understanding of exactly what it is that i want it to do it goes like this.... My girlfriend got a message from a friend that was all in ones and zeros, and no its not because something on one of the mail servers is messed up he meant for it to be that way. But through the process of converting the 8 digit binary numbers into decimal values so that the corresponding ANSI character could be found I decided that it was taking to damn long so i would just write a prog to do it for me and then i could send back an annoying long message to that guy with ease. Only there is a catch over the summer i went from hotshot for a newb to a newb without a clue, i more or less didnt write a single line of code over 4 months and now i am having problems.
I wanted to write a program that could-
-convert long strings of chars into all 8 digit binary code
-as well as convert large blocks of 8 digit binary back into ANSI letter values and then ANSI characters
-I want it to use a frame and have a relativly simple usage procedure
Now that you know what i set out to do I can show you how far i got -

OK so other than that i decided to play with some of the paint functions i more or less stayed on task, at first i had it just convert 8 digit binary nums into decimal form using this -
int ctr=1, decimal=0;
for (int i = a.length()-1; i>=0; i--)
if(a.charAt(i)=='1') decimal+=ctr;
ctr*=2;
which i found in someone elses post and made some changes to, thank you someone whoever you are i hope you see this, anyways,.. then i decided i wanted it to check the length of a string and divide it by 8 assuming that it it a perfect block of 8 digit nums and then cut it into substring and go through the proccess of converting the binary to deciaml one piece at a time. I did it more or less, well it compiles right but whenever you put in more than one 8 digit binary number it ends up giving you some really strange decimal numbers and i cant seem to figure out why the hell it is doing this.??? I was hoping that some one could help me out.

Hello
In extractor and ODS I have key figure type floating.
Sometimes extractors return value '0' for this field.
In such cases, in update rules, I fill KF using FM CONVERT_TO_LOCAL_CURRENCY.
Problem is when I read value '4.1' i get '4.099999996E00' in KF instead '4.100000006E00'.
How to resolve this problem?
THX
AdamHi Kumar
It is not reporting problem but calculating.
I use this KF to calculate another.
This small difference give disparity in large values.
Multiplication
1.000.000 x 1,1 = 1.100.000
but
1.000.000 x 1,0999999996E+00 = 1.099.999
I must insert to KF value 1,1000 not 1,099999999.

Hi,
In Export invoice we are entering currency in USD.When we enter the value it accepts 3 decimal places.But it is stored as 2 decimal places in table.
Eg.2.059 USD in invoice screen
but in table 20.59 USD.
What is the problem?where we can rectify this error?It will be stored with two decimal places. No issues with that. when you display this on your report, you have to specify the currency as USD and your issue will be resolved.
write: v_amount to v_amount currency 'USD'.
I am quoting from the help of the write statement below.
This addition defines currency-dependent decimal places for the output of data objects of data types i or p. For all other data types, except for f, the addition is ignored. For cur, a three-digit, character-type field is expected that contains a currency key from the column CURRKEY of the database table TCURX in uppercase letters. The system determines the number of decimal places from the column CURRDEC of the respective row in the database table TCURX. If the content of cur is not found in TCURX, two decimal places are used. The following applies for numeric data types:
In the case of data types of type i, a decimal separator is inserted at the position determined by cur and the thousands separators are moved accordingly.
In the case of data objects of type p, the decimal places defined in the definition of the data type are ignored completely. Irrespective of the actual value and without rounding actions, the decimal separators and the thousand separators are inserted at the positions in the numbers determined by cur.
In the case of data objects of type f, the addition CURRENCY has the same effect as the addition DECIMALS (see below). Here, the number of decimal places is determined by cur.
If the addition CURRENCY with length specification * or ** is used after AT, it is used first and the output length is determined from the result.
Note
The addition CURRENCY is appropriate for the display of data objects of type i or p without decimal places, whose contents are currency amounts in the smallest unit of the currency.
Example
The output of the WRITE statement is "123456,78".
DATA int TYPE i VALUE 12345678.
WRITE int NO-GROUPING CURRENCY 'EUR'. -
I'm having a float drop issue with my layout. I've read
several articles on this but can't figure it out, because my layout

*I then have a top horizontal navbar, also a <div>, no

Floating point problem in method
When I got a method, like moveTo(float,float), originally, it should be, for example moveTo(30.45f,100.894f). But if I passed an array which id of type float but don't have the 'f' at the back. Does this matter? An Example:
float x1Points[]=new float[ix.length];
float y1Points[]=new float[iy.length];
for(int i=0;i<ix.length;i++){
x1Points=ix[i]*100000-299900;
y1Points[i]=iy[i]*1000-101710;
GeneralPath polygon = new GeneralPath(GeneralPath.WIND_EVEN_ODD);
polygon.moveTo(x1Points[0], y1Points[0]);//problem here
for ( int i = 1; i < x1Points.length; i++ ) {
polygon.lineTo(x1Points[i], y1Points[i]);
g2d.draw(polygon);No, this does not matter.
The "f" is only for numeric literal values, to indicate that the value is a float, instead of an int or double (which it is by default).
For variables, there is no need to specify the type with a postfix letter like the "f", because the type of variables is always known; for example, the compiler already knows that you have an array of floats, so there is no need to tell the compiler again that you want to pass floats to the method.

Hi,
I wish to know how can I get the floating point to two significant digit?
like 0.012234455 to 0.01?public class TaDa {
public static void main(String[] args) {
double percent = 2 / Math.PI * 100;
System.out.printf("%.2f", percent);
}The string starting wth % is a format string. The ".2" means you want 2 decimal
places. The "f" means you are dealing with a floating point thing.
There is also String.format("%.2f", percent) which will return a String - the same
one as is printed in the example. These methods became available with Java
1.5 and are documented here:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Formatter.html
(A similar printf is available in PHP). -

Showing a floating decimal in a adf table
hi there,
i hava created a adf table out of a data control, the problem in the bean i have strings and a double value.
The strings a shown, but the double value (very tiny values like 1.36E-6) are rounded to 0, but thats isnt well in my case....
so how can i show the floating point notation???
thx
grettings
hannesWhere do you get the floating point numbers from? From the db via an entity object (EO) or a view Object (VO) or from an EJB?
You only mentioned that you used a data control.
If the values are read from the DB and your business layer uses EOs and/or VOs, you go to the model project, search the EO in question in the application navigator and double click it. Then select the 'Attributes' section of the wizzard and follow the instructions from the previous posting.

Decimal Problem in Document Amount..
Greetings for the day,
In table amount showing properly. I mean decimal showing only 2 digits but
in my document it is showing 3 digits. Earlier it was worked properly but
since today morning I am facing this problem. I checked in T.code OY04
there is no option for 2 decimals hence I haven't maintained local currency
with any of the available options(1,3 or 5). So how to set in document
decimals as 2 digits?
Kindly revert me back as soon as possible with your valuable suggestions.
Thanks & Regards,
Vinod.Just check in OY01
SU3 - User profile
Do not give anything in OY04 - I have checked for my currecny GBP. I don't even find my currency in OY04
It seems this setting is not needed
Thanks
