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.

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());
      
 }
}

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());
      
 }
}
