Java Primitive Type Conversion Elegance

Dear programmers,

public class Convertion {

  public static void main(String[] args) {

    final float CONVERTION_RATE = 200.482F;
    float given_number = 3772.46F;

    System.out.println("€" + given_number + " = " +
                      (int)(given_number * CONVERTION_RATE) + " Escudos");
  }
}

This is a little code I made to convert a given number of euros (3772,46 in this case) to portuguese 'escudos'.
I would like to make the primitive type convertion more elegant.
Since the 'escudo' lost its fractional value, I think that some floor/ceiling thing it's probably needed here.

(Yeah, this is a 4 years-old programming exercise, made when the Euro was dandy...)

Thank you, programmers.

There is no such thing as elegance in Java, only scalable web 2.0 enterprise cluster

It's XXX€, not €XXX like dollars.

Actually, either is valid

And €x is much more common.

x€ is more common here

no one cares about your ass-forwards country

When something is 2 metres long (or 2 Koala noses, or whatever retarded measure Americans have), do you say "m 2" or "2 m"?

When you say something is "2 metres", do say "it's two metres" or "it's metres two"?

Amerikans use Furlongs for measurements IIRC.

itss metter not metree yuo iddiott

Here is a better version of your code, faster, more evolutive and elegant:

(defun escudos->euros (n)
  (* 200.482 n))

(setf given_number 3772.46)
(format t "~d Euros = ~d Escudos"
        given_number
        (escudos->euros given_number))

Convertion is easy!!! 25.34 furlongs = 123.4439 inches
and 74635.23 inches = 1 koala nose = 123463555.32378 texas tea spoons.

actually NO, the Euro sign is written AFTER the number, that's all.

loooooooool Assmericans.

import java.math.BigDecimal;
import java.math.MathContext;

public class Main {
  
   
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {

        // java 1.4.2 solution
        final float CONVERTION_RATE = 200.482F;
        float given_number = 3772.46F;

        System.out.println("€" + given_number + " = " +
                          (((float)Math.round(100 * given_number * CONVERTION_RATE))/100) + " Escudos");
           
        // java 5 solution      
        BigDecimal convRate = new BigDecimal("200.482");
        BigDecimal ammountCur = new BigDecimal("3772.46");
       
        BigDecimal result = ammountCur.multiply(convRate);
        System.out.println("Raw : ");
        System.out.println("\tresult == " + result.toString());
        System.out.println("Rounded : ");
        System.out.println("\tresult == " + result.round(MathContext.DECIMAL32).toString());
    }
   
}

The J2SE 5 solution is better. It allows you to keep the precision internally and then round directly on the BigDecimal.
You can also set the rounding rules using a MathContext, something you can't really do elegantly in J2SE 1.4.2.
[You could use BigDecimal in the J2SE 1.4.2 solution but you would still need to convert back to the float primitive type before rounding.... nasty. No wonder they improved BigDecimal]

I am pleased that my ass is backwards.

IT'S SPELLED CONVERSION, YOU IDIOTS

>>21
YHBT. YHL. HAND.

your code is beautiful, I learned volumes from it

Estúpido!
Nessa altura bastava ir ao google e meter: 3772.46 PTE in EUR
Agora já não dá mas podes ver que o dólar é merda* com: 1 EUR in USD
ou 1 € in $

*dólar é merda = dollar is shit

IT'S CONVERSION

IT'S CONVERTHE GAMEION

I lol'd

Do it like a nigger would, just wget a request to Google and sed the answer.

Yeah, this is a 4 years-old programming exercise

If it's meant for 4 year olds, why are you having so much trouble with it?

maybe he's only 3 years old

Stop posting on /prog/ and come home.

I'm feeling really keen, for some of that good ol' green

Marijuana MUST be legalized.

convert a given number CONVERTION RATE Escudos.
