Dealing with exponents for double values...

Hi all,
I've been putzing around with the NumberFormat class, as well as the Double api, but I can't seem to find a solution on how to remove exponents from double values.
For example:
double x = Double.MIN_VALUE;
Might return 4.9E-123
How do I remove the E, or any of those special characters, and just retrieve the exact, unshortened value?

For example:
double x = Double.MIN_VALUE;
Might return 4.9E-123It doesn't return 4.9E-123. It returns a double. If you print it out it will look like that.

How to solve NaN error, while dealing with multiplication of double values

i am getting NaN error in the program.
consider this following code
for (j=0;j<nh;j++)
sum = 0.0;
for (i=0;i<ni;i++){ sum = sum + (ai[i] * wi[i][j]) ;}
//System.out.println(sum);
ah[j] = sigmoid(sum);
public static float sigmoid(float x)
return ((Math.exp(x)- Math.exp(-x)) / (Math.exp(x)+Math.exp(-x)));
ni = 2500-- no of input nodes;
nh = 5000 -- no of hidden nodes;
i am getting problem in calculating the "sum" value. its returning NaN for "sum".
here a[i] values are around some +/- 0.XXXXXXXX upto 14 digits
and wi[j][j] values are also +/- 0.XXXXXX upto 14 digits.
all values are of datatype double.
i was stucked up with this problem. what i am to do?
give me suggestions..
please reply me

This can occur with double divisions. I wrote a small method that solves this:
     * Set double values that have a value of 'NaN' or 'Infinity' to 0.0. This can happen when dividing double values as they
     * don't cause a DivisionByZeroException.
     * @param value Double value to check.
     * @return Input value with 'NaN' and 'Infinity' set to 0.0.
    static public double resetNaN(final double value, final double resetValue) {
        return (Double.isNaN(value) || Double.isInfinite(value)) ? resetValue : value;
    }//resetNaN()

Stacked 100% bar chart - Problem with datatips for zero value data points

I have a stacked 100% bar chart that shows datatips in Flex 4.   However, I don't want it to show datatips for
data points with zero values.   Flex 4 shows the datatip for a zero value data point on the left side of a bar if the data point is not the first in the series.
Here's the code that illustrates this problem.    Of particular concern is the July bar.    Because of the zero value data point problem, it's not possible to see the datatip for "aaa".
Any ideas on how we can hide/remove the datatips for zero value data points ?        Thanks.

How to keep 2 decimal places for double value

Hi,
I need rounding function, which should round a double number till 2 digits, if there is no decimal part it should append 2 zero's in decimal places.
eg. 100 --- > 100.00
200.234 --> 200.23.
I tried with Number class. but it is returning string, from that string if I try to convert to double value, it is rounding off one digit.
Can any one help on this problem.
Thanks,
Suman.ch

I am using xmlBeans using that I need to write this
rounded value into a xml file, for that I need only
double value with 2 decimal places.You can probably write the value as a String instead of a double somehow, so you can use the DecimalFormat class.
You could try their mailing-lists for users/developers:
http://xmlbeans.apache.org/community/index.html

Problems with convertNumber and Double values

I've serious troubles using convertNumber with Double data in input fields.
While output formatting works fine, the outputted string fails to be converted back - I get conversion errors.
So the value that is written to the input field generates a conversion error being submitted! This is not good practice!
I've found out the following: (I use german locale, so following examples containing ',' means decimal point)
<f:convertNumber pattern="##0.00" />generates the right output, eg. for Double(20.50) - "20,50", but this value ("20,50") will not be parsed using the above pattern! Only values with non zero last minimum fractional digit (eg "20,51", "20,59", ... ) will be parsed!
In addition, the above pattern doesn't parse numberstrings that don't contain all significant digits.
For example an input of "20" will not be parsed to "20.00"!
Maybe this is not the right forum for that problem, since i think this is a general java formatting problem (?).
But as the problem arised by using the convertNumber tag and acting like this on numeric input fields is not very comfortable, I liked to post this here. Maybe someone can give me some advice?

I also have found this problem, except that in my experience it is the decimal part that must be non-zero, not just the last digit of the decimal part. So with a pattern of "0.00" the string "1.50" (one and a half) will be accepted whereas the string "1.00" will not.
My guess (just a guess) is that it is related to the documented behaviour of the DecimalFormat object when it parses a number. According to the documentation:
The most economical subclass that can represent the number given by the string is chosen. Most integer values are returned as Long objects, no matter how they are written: "17" and "17.000" both parse to Long(17). Values that cannot fit into a Long are returned as Doubles. This includes values with a fractional part, infinite values, NaN, and the value -0.0. DecimalFormat does not decide whether to return a Double or a Long based on the presence of a decimal separator in the source string. Doing so would prevent integers that overflow the mantissa of a double, such as "10,000,000,000,000,000.00", from being parsed accurately. Currently, the only classes that parse returns are Long and Double, but callers should not rely on this. Callers may use the Number methods doubleValue, longValue, etc., to obtain the type they want.
Which means that "1.50" will be returned as a Double while "1.00" will be returned as a Long. Perhaps there is then a class-cast exception whie trying to use this value?
If this is indeed the problem, the solution is to use the getDouble() method of the parsed Number to create the Double to be returned, but this is for the implementer to do - not the user!

How to deal with credentials for external applications using a Java Client/

Hi Guys,
This is the case. I am integrating an external application with an ADF Application. I have implemented some programmatic ViewObjects that are being filled up by a REST Java Client Wrapper. Everything is working fine but the issue is that the credentials the wrapper is using are hard coded inside the java class. I am thinking to ask for the credentials at the beginning of my taskflow and then store them somewhere and use them then to create my client wrapper (passing them in the constructor).
However, I don't know if my approach is good and I would like you to share your experiences or how to deal with this.
Regards

You can use Credential Store Framework to store the credentials securely in the weblogic server instead of hardcoding in the java class.
The Credential Store Framework:
- enables you to manage credentials securely
- provides an API for storage, retrieval, and maintenance of credentials in different back-end repositories
Check the documentation on CSF API -
http://docs.oracle.com/cd/E29505_01/core.1111/e10043/devcsf.htm
Major Steps -
1. Create a credential map and key in em console to store the password (http://docs.oracle.com/cd/E25054_01/core.1111/e10043/csfadmin.htm)
2. Use CSF API to retrieve the stored password
3. In jazn-data.xml give permissions to access CSF key and map

Hi Kamlesh,
Thanks for your response.
Actually, In the "Process External Bank Statement" window, i see that there are few entries which is for the previous year and which has not been reconciled. I have never worked practically on BRS and hence, i am scared to make any changes in the clients database without being confident on what i am doing. I need to reconcile for one of their Bank a/c for the month of April '08. I have the copy of the statements for the month ending 31st Mar 08 and 30th Apr 08. The closing balances are as below:
31/03/08 - 2300000.00
30/04/08 - 3100000.00
Now my OB for Bank a/c for April '08 in SAP is 2300000.00 Dr.
When i go to External Bank Reconciliation - Selection Criteria Screen (Manual Reconciliation), here are the detail that i enter:
Last Balance: INR -7,000,000.00000 (Grayed out by the system)
Ending Balance: INR -3,100,000.00000 (Entered by me)
End Date: 30/04/08 (Entered by me)
"Reconciliation Bank Statement" Screen opens up and shows the below balances in the screen:
Cleared Book Balance: INR -7,000,000.00000
Statement Ending Balance: INR -3,100,000.00000
Difference: INR 3,800,000.00000
As per the Bank statement, i have found all the transactions listed out here for the month of Apr '08 but, i also found that the open transactions for the previous month from April '08 have been lying in "Process External Bank Statement" window.
Could you please help me solve my issue as to what needs to be done or could you also get me some links from where i can get few documents for processing External Bank Reconciliations?
That will be of a great help for me. I need steps as to what needs to be done first and then the next so that i can arrive at the correct closing balance for the month April '08.
Thanks in Advance....

Query registry with powershell for certain value

Hi,
Ever since Windows 7 we are having trouble with USB-printers. For some reason they get disabled ever so often.
The only solution we have then, (that works) is to fully remove and re-install the device.
However, we give our printer a specific name "loketprinter". If you remove the printer, some values with "Loketprinter" remains in the registry. These are located in various locations troughout the registry.
Therefore i'm looking for a fast way to query and delete values or keys that contain "loketcomputer".
I want to search the whole register.
Could you please get me on my way?

after some googeling and reading the help file i've created the following:
Get-ChildItem HKCU:, HKLM: -Recurse -Include *Loket* -ErrorAction SilentlyContinue | Select-Object -ExpandProperty Name
This only find parts of it, but at least its something.
Its really slow though

How to deal with BRS for the below scenario?

Hi,
I would like to know the solution for the below scenario for BRS:
I have a customer who was maintaining their accounts with Tally software for their previous Financial Year. This year they have shifted to SAP B1 2005B. They have issued few cheques for their vendors in the month of march 2008 which has been realised in the month of April 2008. As per Tally, the closing balance of their bank is 8 Lakh but as per the bank statement, their closing balance is 23 Lakhs. In SAP, the opening Balance for the bank is considered as 23 Lakhs. Now there are 15 Lakh worth cheques which were not realised for the month of March 2008.
Example:
abc a/c - 3Lakh
def a/c - 5lakh
xyz a/c - 7 lakh
How do i reconcile for this scenario and what procedures do i follow in SAP?
Thanks and Regards,
Kaushal

I cannot import music into my iTunes or import cps, getting error (-50). HELP!! been dealing with this for 2 days

I am going crazy. Got a new 2tb time capsule and have moved all my music to it and thought I was finally successful (though I have somehow lost some songs and recovered some...though some still cut off right at the end??) but now my biggest issue is itunes will not allow me to import any music, cd or downloaded files. I get the message when importing a cd "error occured while importing the file "song name" An unknown error occured (-50). I get the same error when trying to add downloaded music files also. I am really getting frustrated, itunes did not use to be so difficult to maintain. If we figure this out maybe someone can also help figure out why some songs are cutting off. I have researched this for a couple of days and unfortunatley am not finding much help. Thanks!!

1. You did not get an error message telling you that your iPhoto library was getting full. You got a message telling you that your HD was getting full, right?
OS X needs about 10 gigs of hard drive space for normal OS operations - things like virtual memory, temporary files and so on.
Without this space your Mac will slow down as the OS hunts for space on the disk, files will be fragmented, also slowing things down, apps will crash and the risk of data corruption - that is damage to your files, photos, music - increases exponentially.
Your first priority is to make more space on that HD. Nothing else can be done until you do.
Purchase an external HD and move your Photos and Music to it. Both iPhoto and iTunes can run perfectly well with the Library on an external disk.
Your Library has been damaged from being run on an overfull disk.
How much free space on it now?

Having trouble with inner for loop values in my procedure

Hi ...
I am using oracle 10g and here is my procedure ...
create or replace procedure sales_information is
v_qty number(10);
rem_qty number(10):=0;
cursor pck_quantity is
select * from sales_info;
cursor no_of_labels is
select ceil(sum(nvl(total_quantity,actual_quantity))/400) from sales_info;
begin
for j in no_of_labels
loop
for i in pck_quantity
loop
select nvl(i.total_quantity,i.actual_quantity) into v_qty from sales_info;
if v_qty>=i.packed_quantity and rem_qty=0 then
insert into sales_order values------------
rem-qty:=v_qty-i.packed_quantity;
v_qty:=rem_qty;
exit;
else if v_qty>=i.packed_quantity and rem_qty>=400 then
insert into sales_order values-----------
rem_qty:=v_qty-rem_qty;
v_qty:=rem_qty;
exit;
else if v_qty>=i.packed_quantity and rem_qty>0 then
rem_qty:=v_qty+rem_qty-i.packed_quantity;
v_qty:=rem_qty;
insert into sales_order values-----------
else if v_qty is null and rem_qty>0 and then
insert into sales_order values-----------
else if v_qty<i.packed_quantity and rem_qty:=0 then
rem_qty:=v_qty;
else if v_qty<i.packed_quantity and rem_qty>0 then
if (v_qty+rem_qty)>400 then
insert into sales_order values-----------
rem_qty:=v_qty+rem_qty-i.packed_quantity;
v_qty:=rem_qty;
end if;
end if;
end loop;
end loop;
The inner for loop will retrieve the same values of v_qty for every iteration of outer for loop when it runs the following select statement:
select nvl(i.total_quantity,i.actual_quantity) into v_qty from sales_info;
and thus loses the previously computed values of v_qty and rem_qty
in the previous iteration of outer for loop whereas i want the inner for loop to iterate over it's previously computed values of v_qty and rem_qty but cant think of a workaround.

Dealing with "video for other Platform/OS" message

Some advice please.
On my home network, I have my WVC200 camera attached to the Linksys router via a cable; and I am able to control the camera and see video from a Vista OS machine. When I try to see video on a wireless laptop, the message "Video for other Platform/OS" appears on the Linksys control screen.
I am able to log in to the wireless camera from the laptop; pan/tilt the camera; but cannot see video on the laptop.
Should I be able to see video on a second PC on the network ?
