Parsing dollar amounts from a string & totalling

[rockies1]

I have a file that has dollar amounts in it in each line of the file.

I need to pull the amount out and total them. Amounts will always have 0, 1, or 2 decimals.

I used doubles, but I end up getting odd totals like this: 17362.899999999998

This occurs even when adding numbers like 569.91 and 419.03. I get 988.9399999999999.

How can I make sure I get the actual amount and not something funky?

Thanks!

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

 public class W{
  public static void main(String[] args){
 
  double x = 569.91 + 419.03; 
  System.out.println(x); 
   
    NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.US); 
    System.out.println(nf.format(x)); 

    NumberFormat nf2 = NumberFormat.getCurrencyInstance(Locale.JAPAN); 
    System.out.println(nf2.format(x)); 

    NumberFormat nf3 = NumberFormat.getCurrencyInstance(Locale.GERMANY);    
    System.out.println(nf3.format(x)); 
  }
}

If you want to parse the values out from Strings.....

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

 public class W{
  public static void main(String[] args){
 
  String s1 = "569.91"; 
  String s2 = "419.03"; 
  double d1 = Double.parseDouble(s1); 
  double d2 = Double.parseDouble(s2); 
  double x = d1 + d2;
  System.out.println(x);     

   try{
   
    NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.US); 
    System.out.println(nf.format(x)); 

    NumberFormat nf2 = NumberFormat.getCurrencyInstance(Locale.JAPAN); 
    System.out.println(nf2.format(x)); 

    NumberFormat nf3 = NumberFormat.getCurrencyInstance(Locale.GERMANY);    
    System.out.println(nf3.format(x));
   
   }catch(NumberFormatException e){System.err.println(e);} 
  }
 }
