displaying a float to 2 decimal places {Resolved} thanks

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.

Code:

---

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:

Code:

---

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.

Code:

---

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());
     
 }
}

Thanks for you help
