Formatting

By default, a number is formatted using RoundingMode.HALF_EVEN. However, we can explicitly set the rounding mode via NumberFormat.setRoundingMode().

Trying to condense this information into a utility class named NumberFormatters can be achieved as follows:

public static String forLocale(Locale locale, double number) {  return format(locale, Style.SHORT, null, number);}public static String forLocaleStyle(  Locale locale, Style style, double number) {  return format(locale, style, null, number);}public static String forLocaleStyleRound(  Locale locale, Style style, RoundingMode mode, double number) {  return format(locale, style, mode, number);}private static String format( Locale locale, Style style, RoundingMode mode, double number) ...
