# Code runs but gives wrong output!

The code is supposed to convert the amount of Yen given into U.S. dollars, but it gives out a slightly wrong answer. Please help. Code is pasted below:

```public static void main(String [] args)    {
Scanner input = new Scanner(System.in);
int sentinel = 0;
double yen = 1;
// every .0089 cents is eqivalent to 1 japanese yen
double conversion;
while (sentinel != 1) {
System.out.println("\nPlease enter an amount of Yen");
yen = input.nextDouble();
if (yen <= 0) {
// if input is 0 or lower it doesn't convert because that's not an
//amount of money
conversion = yen;
System.out.printf("Not valid amount of currency. Try Again.");
} else if (yen >= 111.98) {
// if the input is greater than or equal to 111.98 yen (1 U.S. dollar) the program
// prints out only the first two decimals to keep it organized
conversion = yen * .0089;
System.out.printf("\nThat is %.2f U.S. dollars", conversion);
} else if (yen < 111.98) {
// If input is lower than 111.98 it prints out the first 4 decimals because
// 1 yen is .0089 cents in the US
conversion = yen * .0089;
System.out.printf("\nThat is %.4f U.S. dollars", conversion);
}
}
}
```

Moderator edited: Added markdown to make the code render properly on the forums.

Hi Timothy! I added some markdown to your code to make it appear properly in the question. If you take a look at the "Markdown Cheatsheet" link at the bottom of the "Add an Answer" section, you can find instructions on how to apply markdown to your posts

Hi Timothy, I haven't executed your code but since it speaks about currencies and convertion types of decimals you could have a quick read about the fact that you shouldn't be using 'double' nor 'float' for this task.

Instead try with BigDecimal (I see a main class in your code so I'm guessing this is not a challenge)

Have a great day.
