Output is 3,141590. Why it is not 3.141590? I am using Eclipse (Java) on a Mac.

public static void main(String[] args) {
 TextIO.putf("%f\n", 3.14159);
}

Thank you

That is because of the Locale. Try this

String.format(Locale.US, "%f\n", 3.14159);

For diferent Locales there are different formats for numbers, dates, encodings, etc.

Comma(,) is coming instead of dot(.). This is because of the locale.

I am giving you one example :

import java.text.NumberFormat;
import java.util.Locale;
public class JavaLocale
{
 public static void main(String[] args) 
 {
 Locale locale = new Locale("da", "DK");
 NumberFormat numberFormat = NumberFormat.getInstance(locale);
 String number = numberFormat.format(100.99);
 System.out.println(number);
 }
}

Output of this code : 

100,99
