   FUNCTION: DBPUT_F

      It automatically unscales and converts data in the user buffer from
      floating point to the specified data type, and writes the converted
      data to the database.  It can only store as much new data in the
      database as the space reserved for when the database was first created.

   PARAMETERS:

      type = pointer to data structure type to which floating point data
             are to be converted

      data  = address of user buffer

      user_nv = pointer to number of values in user buffer

      nbad = pointer to number of values set to BAD because of rescaling/
             conversion to a value outside range

      ierr = pointer to error code
