Examples of java.text.DecimalFormatSymbols

java.text.DecimalFormatSymbols
This class represents the set of symbols (such as the decimal separator, the grouping separator, and so on) needed by DecimalFormat to format numbers. DecimalFormat creates for itself an instance of DecimalFormatSymbols from its locale data. If you need to change any of these symbols, you can get the DecimalFormatSymbols object from your DecimalFormat and modify it. @see java.util.Locale @see DecimalFormat @version 1.46, 02/27/06 @author Mark Davis @author Alan Liu

   @param d      Number of digits after the decimal.
