A DESCRIPTION OF THE REQUEST :
Please provide a member function for changing the rounding method in the NumberFormat class. Only the ROUND_HALF_EVEN method is currently supported and it would be convenient to be able to set it to ROUND_FLOOR or ROUND_CEILING depending upon the application needs.

JUSTIFICATION :
It is necessary to manually perform any rounding method other than ROUND_HALF_EVEN prior to the call to format function if one needs to use a different rounding method based on application specifications, it would be much more convenient to be able to specify a different default method to the NumberFormat instance as one can do with BigDecimal. Thanks.
