re-define the missing values

Hi All:

Suppose I have a multidimensional array (time, lev, lat, lon) with missing
values '-32768'. How can I change the missing values to '-999'? The
following is what I did, but it does not work.

  v = short2flt(f1->V)
  v@_FillValue = -999
   printVarSummary(v)

The following is what I got:

Variable: v
Type: float
Total Size: 1014398976 bytes
            253599744 values
Number of Dimensions: 4
Dimensions and sizes: [T | 1821] x [P | 17] x [Y | 64] x [X | 128]
Coordinates:
            T: [-1247.5..572.5]
            P: [1000..10]
            Y: [-87.8638..87.8638]
            X: [ 0..357.1875]
Number Of Attributes: 9
  valid_min : 5
  long_name : meridional wind
  units : M/S
  file_missing_value : -32768
  time_op : average
  _FillValue : -999
  missing_value : -32768

Best!
