How to deserailize BigDecimal in C++

Hi,
I'm not able to deserialize big decimal object in oracle coherence cache by c++?
if I read this big decimal value as object then how I'm going to read this value?
Please share your thoughts..
Thanks and regards,
Sura

I don't think we have an equivalent of BigDecimal in our C++ POF implementation. You probably need to write your own deserializer.
Thanks,
Wei

How to pass BigDecimal as currecny to Crystal Reports using JRC 11

Im using JRC to load and view crystal reports.ie loading crystal reports that are created (not by me) using Crystal Reports v 10. My work is just load those rpt files using JRC thick client.
rpt files are bound to .mdb (MS Access) database and DB is password protected. One of the table in database has currency data type. I'm creating a POJO class to implement the table structure. To match with Currency type, Im using BigDecimal type in my pojo class. when i open the .rpt file in crystal report designer, it shows with default currency symbol (i.e $ and £) But the when i load the same report via JRC, It doesnot show the symbol at all.
When I change this to String and pass symbol, it is coming up properly. But in some places, the reports use sum function of 2 curency fields. So in this case, string cannot be used.
Any help would be appreciated.
Thanks.

Sorry. I did not get your point directly.
So I'd recommend not directly relying on internal handling of BigDecimal. You can still report off the value.
So you are telling me not to use BigDecimal? If not what should I use? Please be bit more explanative.
Thanks.

How to send a bigdecimal by DataOutputStream

Hi Folks!
Can anybody tell me how i can send a bigDecimal to my client through DataOutputStream object. There are methods in DataOutputStream class for sending long,int,string,double,short and so on BUT there is nothing for bigDecimal.
Here is my code.
Socket cs;
DataInputStream br;
DataOutputStream dos;
public void run(){
try{
     BigDecimal bd = new BigDecimal ( 12342342.234234 ) ;
     bd = bd.setScale ( 1, BigDecimal.ROUND_DOWN ) ;
     System.out.println ( bd ) ;
   //here how i cant send my BigDecimal those dos object?
   dos.
}catch(Exception e){}
}Thanks in Advance

you are correct there is a method bytevalue() in bigDecimal class. which conver my bigDecimal value into bytevalue. WORKS FINE. but on the client side when i receive "BYTEVALUE()" how can i bring it back to the original. Because ofcurse i am gettin my coverted byte value not the original value of bigDecimal..
Here's how i convert Bigdecimal into bytevalue
     System.out.println("Original "+bd);
     dos.writeByte(bd.byteValue());
     System.out.println("BigInt byte values. "+bd.byteValue());
     dos.flush();now on client side thats how i read it,, BUT bytevalue not the original
    byte b = br.readByte();
    System.out.println("I got byte value of bigint " + b);
Thanks in advance

BigDecimal formatting -- Please Help!!!

Hi all,
Could anyone please tell a Java newbie how to format BigDecimal? I have a variable defined as BigDecimal. I am displaying that value in a JTable. I need to format the value with commas but not cents.... i.e. 23,245 not 23,245.24. Is this possible and if so, how?
Please help!!!
Thanks in advance.
Lynn

Hi,
try
java.math.BigDecimal big = new java.math.BigDecimal(23245.24);
java.text.DecimalFormatSymbols symbols = new java.text.DecimalFormatSymbols();
symbols.setGroupingSeparator(',');
java.text.DecimalFormat formatter = new java.text.DecimalFormat("###,###",symbols);
String res=formatter.format(big);
you can then put the res String in the JTable

Looking for examples using BigDecimal

Two newbies to Java are looking for examples of code that use the BigDecimal features for rounding and truncating large numbers to more user-friendly values.
We are doing some hefty math calculations on values defined as doubles and want to round and truncate to within 1/100th for display purposes.
We've tried some stuff on our own, but it is not cooperating. Any help would be greatly appreciated!

Here is a good article of how to use BigDecimal

Atlast I found out what the problem ...was ... !!!
If u have any problem like this please check the DB2 or the database that u r using ...
Any Numeric Coumns in Database would be having a precision and the Scale field ...Check these fields. If the scale is defined as Zero ...then the Numerical Value u r trying to insert will be truncated ...

How to get a BigDecimal from german number (12,34)?

How can i convert a string "12,34" to a BigDecimal object (value of 12.34)?
I tried using special locale NumberFormat, but this doesn't work:
     * Convert a string to a BigDecimal object.
     * @param string String to convert.
     * @param pattern Pattern format to parse input string.
     * @param locale Locale to use for text formatting.
     * @return BigDecimal BigDecimal object with value represented by <I>string</I>
     * or null if conversion failed or <I>string</I> is empty.
    public static BigDecimal toBigDecimal(String string, String pattern, Locale locale) {
        BigDecimal result = null;
        if (string != null) {
            if (pattern == null) {
                pattern = "###,###,###,##0.####"; //default
            if (locale == null) {
                locale = Locale.getDefault(); //default is GERMANY anyway ...
            DecimalFormat df = (DecimalFormat) NumberFormat.getInstance(locale);
            df.applyPattern(pattern);
            Number num = df.parse(string, new ParsePosition(0));
            if (num != null) {
                try {
                    string = string.replace(',', '.');
                    result = new BigDecimal(string);
                } catch (NumberFormatException nfe) { /* ignore */ }
        }//else: input unavailable
        return result;
    }//toBigDecimal()this code only works for string "12.34" but not for "12,34" (german style)... ?

no, num.doubleValue() is not exact enough (can lead to different numbers after the decimal point). the only way i have found so far to convert exactly is to use the String constructor of BigDecimal.
the starnge thing is, that the same value as a fixed string works, but not the string value:
    public static BigDecimal toBigDecimal(String string, String pattern) {
        BigDecimal result = null;
        if (string != null) {
            java.text.DecimalFormat df = new java.text.DecimalFormat(pattern);
            Number num = df.parse(string, new java.text.ParsePosition(0));
            if (num != null) {
                try {
                    string = string.replace(',', '.');
                    System.out.println("1: "+new BigDecimal("12.34"));
                    System.out.println("2: "+new BigDecimal(string)); //thorws NumberFormatException, even though string has the value "12.34" (checked with debugger)
                    result = new BigDecimal(string);
                } catch (NumberFormatException nfe) {
                    System.err.println("toBigDecimal():"+ nfe);
        return result;
    }//toBigDecimal()output:
1: 12.34
toBigDecimal():java.lang.NumberFormatException: 1234
where is the decimal point? the debugger shows that 'string' has the value "12.34" (with decimal point)????

How to call a AS/400 Stored Procedure with a BigDecimal Value?

Hi,
Could you pls tell me how to call a stored procedure on the AS/400 which request an input value of packed decimal(10P 4) value.
I have tried to convert it to a BigDecimal in Java and call the stored procedure as follows but it gave me a decimal point error on the AS/400.
Could you pls show me where I'm wrong in the following code.
Thanks
Jan
========Java program to call AS/400 Stored procedure with setBigDecimal()===========
//Assign the value to String
string sBDVal = "30"
//Convert the String value to BigDecimal

// Set in parm values
callSP.setString(1,"Value 1");
callSP.setBigDecimal(2,bdAmt);

// Register out parameter

Could you pls show me where I'm wrong in the following codeI don't know, you're doing a lot of things I have never tried. But "decimal data error" most likely means that the stored procedure is expecting packed data and the driver is giving it zoned data, or vice versa. You could confirm that by dumping your variables inside your RPG. If that is your problem, you could work around it by redefining your BDAMT parameter as integer or string and reformatting it in the RPG.

How can I validate value of BigDecimal into af:inputText??

I have a af:inputText which value is binded a BigDecimal value.
The big decimal value is held in DB with number format NUMBER(10,2),
to validate this value, what types of validation technique should to be used?
NUMBER(10,2) , user is able to enter value with format just 10,100 or 10.02 etc.
The format with comma 10,2 the page automatically validate the value with message "java.lang.NumberFormatException", also how can I change this message.
<af:inputText value="#{Page1Bean.bank.balance}"/> // balance is BigDecimal

Hi again,
I can just point you to these links:

How to deal with bigdecimal in DataProvider getValue method

Dear Sir/Madam
Trying
employeeDataProvider.getValue("EMPLOYEE.NUMBER0")
gives an error .
My Database is Oracle. EMPLOYEE.NUMBER0 is NUMBER(5).
Databound shows EMPLOYEE.NUMBER0 to be bigdecimal.
please advise how to deal with bigdecimal to be able to execute
employeeDataProvider.getValue successfully.
Thanks a lot for your kind assistance
Salah Beidas

employeeDataProvider.getValue("EMPLOYEE.NUMBER0")
gives an error .What is the error? Does red x appears in the margin in the Java source editor? If so, when you place the curson over the red x, the tooltip shows the error. What does it say.
Is it a runtime error? Does a page show with a stacktrace? If so, what is the error? When you look at the stack trace do you find your page mentioned anywhere. If so, it shows a line number. What does that code look like (that is pointed to by the line number)?

How to parse a BigDecimal from a localized number String

I want to be able to build a BigDecimal instance from a localized String.
i.e.: From a string like "2.123,45123" I want to get when I get by doing: new BigDecimal("2123.45123");
The NumberFormat parse(String) method answers doubles, so I lose presition. When I do nf.parse(2,0000000000000000001) y get a Double representing 2. I can't make a BigDecimal from such a string afaik.
The problem is the localized version on the number (in the string) otherwise it works fine (with the US locale).

>>
So you only can't convert a string to a BigDoublethat
uses the ',' for the decimal place and the '.' forthe
real number separators? If that's the case, whycan't
you use a String buffer then to strip out all the
periods and replace the comma with a period so it
looks like a US decimal string then use that?Thank you very much for your answer. That would have
been a workaround. I found a BigDecimal parser that's
absolutely perfect for the task.

Gives to BigDecimals what java standard gives to all
the other Number subclasses. Good! Frankly, I'm usually just lazy enough to hack a solution.... because I like to say that I hack. evil laugh

BigDecimal: how to keep 2 fraction digits, round up.

Hi,
To calculate money amount, we need to have 2 fraction digits.
For example,
8888.567 --> 8888.57
99998888.865 ---> 99998888.87
0.982 --> 0.98
for method round(MathContext), the mathContext specifies total number of digits, not fraction digits.
The workaround we have to use:
amount.divide(new BigDecimal("1"), 2, RoundingMode.HALF_UP);
what is the right way to achieve 2 fraction digits/half-UP?
Thanks for help.
Dave

When handling money you are better off not using decimals. You can either create your own Money class which has 2 variables: dollars and cents. Or use ints for all calculations and then simply divide by 100 when you want to display. So one dollar fifty is int of 150 and not double of 1.5.

How to convert Erik Anderson to BigDecimal?

Hi,
I have a Table field Value Author and the String is 'Erik Anderson'
I want to convert this intoa BigDecimal. Here is the code::
BigDecimal bg;
Object valueObj = getObject(columnIndex);
String value = valueObj == null ? "" : valueObj.toString();
bg = new BigDecimal(Integer.parseInt(value));
I am getting Error
For input string: "Erik Anderson"
Please Help!!

Hi,
Thank you all for the reply!
I am using Crystal reports Xi and made a ResultSet Object and set this as ReportSource and when I want this to be viewd through Crystal, it is pulling the Data from the ResultSet and for the column Author, which I defined as a String, it gets the value 'Erik Anderson' correctly and calls for getBigDecimal.
I have no clue why it should convert a String to BigDecimal to display it
However
bg = new BigDecimal("ADHHDJH HDAHKDH HDAHDHA");
should work as per the API.
I am not sure what the result should be. Can some one explain?
