     The following equation is used:

       dst[i] = src[i] * 2**shift



     See the following table for  available  variations  of  this
     group of data type convert functions.

     [*] Each row represents a  source  data  type.  Each  column
     represents a destination data type.

PARAMETERS
     Each of the functions takes the following arguments:

     dst      Destination signal array.


     src      Source signal array.


     shift    Left shifting factor.


     n        Number of samples in the source signal arrays.


RETURN VALUES
     Each of the functions returns  MLIB_SUCCESS  if  successful.
     Otherwise it returns MLIB_FAILURE.
