Hello

I am using a float to give a anwer in dollars, but how can l display the currency to 2 decimal places.

e.g.

416.66

Thanks in advance

I guess you could do it like this.

import java.text.*;
import java.text.NumberFormat.Field;

public class F {
public static void main(String[] args) {

double d = 3.333333333333;
StringBuffer sb = new StringBuffer();
DecimalFormat df = new DecimalFormat();
df.setMaximumFractionDigits(2);
df.format(d, sb, new FieldPosition(Field.DECIMAL_SEPARATOR));

System.out.println(d);
System.out.println(sb);
}
}

Since you are working with currency i guess this would be a better snippet. :lol:

import java.text.*;
import java.util.Locale;
import java.text.NumberFormat;
import java.text.NumberFormat.Field;

public class F {
public static void main(String[] args) {

NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.US);
String field1 = args[0];
String field2 = args[1];
double d1 = formatPlaces(field1);
double d2 = formatPlaces(field2);
double temp = d1 + d2;
System.out.println(temp);
String s = nf.format(temp);
System.out.println(s);


}
public static double formatPlaces(String field){

StringBuffer sb = new StringBuffer();
DecimalFormat df = new DecimalFormat();
df.setMaximumFractionDigits(2);
df.format(Double.parseDouble(field), sb, new FieldPosition(Field.DECIMAL_SEPARATOR));
return Double.parseDouble(sb.toString());

}
}

:sick: sorry forgot the error handling.

import java.text.*;
import java.util.Locale;
import java.text.NumberFormat;
import java.text.NumberFormat.Field;

public class F {
public static void main(String[] args) {
try{
NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.US);
String field1 = args[0];
String field2 = args[1];

double d1 = formatPlaces(field1);
double d2 = formatPlaces(field2);
double temp = d1 + d2;
String s = nf.format(temp);
System.out.println(s);

}catch(Exception e){System.err.println(e);}

}
public static double formatPlaces(String field) throws NumberFormatException{

StringBuffer sb = new StringBuffer();
DecimalFormat df = new DecimalFormat();
df.setMaximumFractionDigits(2);
df.format(Double.parseDouble(field), sb, new FieldPosition(Field.DECIMAL_SEPARATOR));
return Double.parseDouble(sb.toString());

}
}
