I wish this help you I need to store the exact values which is in a csv to a database. The columns has money values . So making use of BigDecimal to store money values. , You can use the constructor with String parameter.
code :
BigDecimal d=new BigDecimal("1");
System.out.println(d.toString());//Will print 1



BigDecimal d=new BigDecimal("1.1");           
System.out.println(d.toString()); //Will print 1.1


BigDecimal d=new BigDecimal("2.50");
System.out.println(d.toString()); //Will print 2.50

BigDecimal locale specific parsing - inconsistency between Wicket's BigDecimalConverter and java.math.BigDecimal

BigDecimal locale specific parsing - inconsistency between Wicket's BigDecimalConverter and java.math.BigDecimal

may help you . The BigDecimal class implements its own validation algorithm on the input, which is throwing the NumberFormatException.
The reason why BigDecimalConverter is parsing 1,3 as 13 is that it is using a raw DecimalFormat behind the scenes. In AbstractNumberConverter.parse(), the getNumberFormat(locale) and parse() methods combination boils down to the following snippet, that takes Wicket out of the equation:
code :
NumberFormat format = NumberFormat.getInstance(Locale.US);
format.setParseBigDecimal(true);
BigDecimal bd = format.parseObject("1,3");
System.out.println(bd.toString()); // Prints 13 !
TextField<BigDecimal> text = new TextField<BigDecimal>(id, model){
    @Override
    public IConverter getConverter(Class<?> type) {
        return new BigDecimalConverter() {
            @Override
            public NumberFormat getNumberFormat(Locale locale) {
                NumberFormat format = super.getNumberFormat(locale);
                format.setGroupingUsed(false);
                return format;
            }
        };
    }
};
text.setType(BigDecimal.class);

This might help you There is a Math.BigDecimal implementation of core mathematical functions with source code available from the Cornell University Library here (also you can download the library as a tar.gz). Here is a sample of the library use:
code :
import org.nevec.rjm.*;
import java.math.BigDecimal;

public class test {
    public static void main(String... args) {
        BigDecimal a = new BigDecimal("1.21");
        BigDecimal b = new BigDecimal("0.5");

        System.out.println(BigDecimalMath.pow(a, b).toString());
    }
}
1.1

BigDecimal round: doubleValue() vs setScale(2, BigDecimal.ROUND_HALF_UP) in price values

To fix this issue I am using all the time BigDecimal for prices, but I was wondering what is the best way to show this to the user. ,
Is using doubleValue() a good way?
code :
BigDecimal bd = ...
System.out.println("bd: " + bd.toString());
System.out.println("bd: " + bd);
double d = 
System.out.printf("%.2f%n", d); // round to 2 decimal places
System.out.println(BigDecimal.valueOf(1.00)
                             .divide(BigDecimal.valueOf(49), 2, BigDecimal.ROUND_HALF_UP)
                             .multiply(BigDecimal.valueOf(49)));
System.out.println(1.00 / 49 * 49);
0.98
0.9999999999999999

this one helps. Is there some way to determine which of two BigDecimal objects is the lower (smaller) number that is simpler than an if or a ternary operator calling BigDecimal::compareTo? , Actually, there's a min method in the BigDecimal class.
code :
BigDecimal min = x.min(y);
