Kotlin Currency Formatting (KCF)

March 05, 2025

There are several ways to achieve this;

1. Using getCurrencyInstance()

NumberFormat format = NumberFormat.getCurrencyInstance();
format.setMaximumFractionDigits(0);
format.setCurrency(Currency.getInstance("EUR"));

format.format(1000000);

2. Using DecimalFormat

NumberFormat formatter = new DecimalFormat("#,###");
double myNumber = 1000000;
String formattedNumber = formatter.format(myNumber);
//formattedNumber is equal to 1,000,000

3. Using getNumberInstance()

int number = 1000000000;
String str = NumberFormat.getNumberInstance(Locale.US).format(number);
//str = 1,000,000,000

Done.
