/**
* 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.
