-/**
- * NumberFormat class.
- *
- * NumberFormat formats decimal numbers in any locale. The decimal
- * number is formatted according to a particular pattern. These
- * patterns can arise from the NumberFormatInfo object which is
- * culturally sensitive. The NumberFormat class can be instantiated in
- * many ways. E.g.
- *
- * <code>
- * //create a invariant number formatter.
- * $formatter = new NumberFormat();
- *
- * //create a number format for the french language locale.
- * $fr = new NumberFormat('fr');
- *
- * //create a number format base on a NumberFormatInfo instance $numberInfo.
- * $format = new NumberFormat($numberInfo);
- * </code>
- *
- * A normal decimal number can also be displayed as a currency
- * or as a percentage. For example
- * <code>
- * $format->format(1234.5); //Decimal number "1234.5"
- * $format->format(1234.5,'c'); //Default currency "$1234.50"
- * $format->format(0.25, 'p') //Percent "25%"
- * </code>
- *
- * Currency is formated using the localized currency pattern. For example
- * to format the number as Japanese Yen:
- * <code>
- * $ja = new NumberFormat('ja_JP');
- *
- * //Japanese currency pattern, and using Japanese Yen symbol
- * $ja->format(123.14,'c','JPY'); //�?123 (Yen 123)
- * </code>
- * For each culture, the symbol for each currency may be different.
