Thread: Simple curency convertor

I'm a Java beginner, i'm writing a simple program to convert pounds to euros, but i would like the output answer to be rounded up to 2 significant figures, can anybody help. here is the code

import java.util.Scanner;
public class EuroConversion {
public static void main(String[] args) {
Scanner input = new Scanner (System.in);

System.out.println("Enter the amount of pounds to convert");
float money = input.nextInt();

double convertion = money * 1.14;


System.out.println("The convertion is " + convertion + " Euros");


}
}

Thanks for any help.

i would like the output answer to be rounded up to 2 significant figures,

Look at the DecimalFormat class.
And also the printf method.

Formatter (Java Platform SE 6)

You could use the String.format() method. It has two parameters . The first is a format identifier, the second is the output string. The identifier starts with
the % symbol. Then you have some optional flags, the width, the significant places, and data type. Here are some examples, and you could do some
searching on Java's String format method: Format a String (JDK1.5) - Real's Java How-to. Also you may want to look into using a named constant for
your conversion rate.

Thanks everyone :-)

package examples;

import java.text.DecimalFormat;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner (System.in);

System.out.println("Enter the amount of pounds to convert");
float money = input.nextFloat();

double convertion = money * 1.14;
DecimalFormat df=new DecimalFormat("#.##");
System.out.println("The convertion is " + df.format(convertion) + " Euros");


}
}


Use this code this will work
