How to format number in "English" numerals only?-CodePudding

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.

CodePudding user response：

You have the right idea but applying it incorrectly. You indeed simply update the locale. However, String.format is syntax sugar, and oversimplified - it can't do that. You have to do what String.format does under the hood use the Formatter class:

import java.util.Formatter;

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