How to format number in "English" numerals only?

The code "%.2f".format(1.221) returns ۱,۲۲ instead of 1.22 on Persian/Arabic/Urdu language devices. How can I make it return always "English" numerals?

I tried "%.2f".format(1.221, Locale.ENGLISH) but it still does not work.

You have the right idea but applying it incorrectly. You indeed simply update the locale. One way is to use the Formatter class:

import java.util.Formatter;
import java.util.Locale;

void main() {
  var fmt = new Formatter(Locale.ENGLISH);
  System.out.println(fmt.format("%.2f", 1.221));
}

UPDATE: I missed some overloads; PrintStream's printf has a Locale variant, as does String.format. Thus, this would also work:

import java.util.Locale;

void main() {
  System.out.printf(Locale.ENGLISH, "%.2f\n", 1.221);
  String example = String.format(Locale.ENGLISH, "%.2f\n", 1.221);
}
