A DESCRIPTION OF THE REQUEST :
I am requesting that 2 new methods be added.
They should be applicable to any numeric type
(including primitives) which contain both an
integer and decimal portion, e.g. double, Double,
etc.  The methods could be added to java.lang.Math.

The methods are:

round(n,d) where n is the number to round and d
is the number of positions after the decimal point.

Unlike the current java.lang.Math.round() method
(a) The return type should be the same as the input type.
    That is round(double,d) should return a double, not a long.
(b) the rounding position is variable.

If n is 0 then the number is rounded to the nearest
integer.  If n is less than 0 then the number is
rounded to the nearest power of 10.
e.g.
	round(123.4567,2)  returns 123.46
	round(123.4567,0)  returns 123
	round(123.4567,-1) returns 120

****

truncate(n,d) where n is the number to truncate and d
is the number of positions after the decimal point.

The return type should be the same as the input type.

If n is 0 then the number is truncated to the nearest
integer.  If n is less than 0 then the number is
truncated to the nearest power of 10.
e.g.
	truncate(123.4567,2)  returns 123.45 (no rounding)
	truncate(123.4567,0)  returns 123
	truncate(123.4567,-1) returns 120

  

JUSTIFICATION :
good to have
