Big Decimal to String

[Marie]

I want to do something like below,

_xmlutil.node("InvoiceAmount", _xmlutil.escapeXML(BigDecimal.toString(i.getInvoiceAmount())))

But toString is not supported by BigDecimal.

How do I convert my BigDecimal value to a string and add as a node in my XML document ?

Thanks
Mei

To get a string representation of a BigDecimal object, just call the toString() method (inherited from Object).

someBigDecimalReference.toString()

If you need particular formatting, get the doubleValue() and format with java.text.DecimalFormat or use the various Formatter convenience methods if you're using 1.5.

Cheers.

:roll:

import java.math.*;
 
public class BigString {
  public static void main(String[] args) {
    BigDecimal big = new BigDecimal("987654321");
    String str = big.toString();
    System.out.println(str);
  }
}

Hi

Thanks for the replies,

It compiled ok,

How do I initialize a BigDecimal number ?

(like double dd = 0D, float ff = 0F)

These are objects, so you instantiate by calling a constructor. For example...

BigDecimal big = new BigDecimal("987654321");

Note that once you have your BigDecimal object(s), you manipulate by calling methods -- not by using operators as you would with primitives.

BigDecimal bigOne = bigTwo.add(bigThree); //NOT bigTwo + bigThree

See the API for info...

Yes, I called the constructor as per http://java.sun.com/j2se/1.3/docs/api/

Amount=new BigDecimal(0D);

Did you note that "the results of this constructor can be somewhat unpredictable"? Compare the API's description of the BigDecimal constructor that takes a double vs. the BigDecimal constructor that takes a String.

(Also, did this work for you? I'm assuming that the variable "Amount" -- which should be lowercase by convention -- was previously declared as type BigDecimal.)

Umm...I think bigFive would be a clearer variable name. :roll:
