Comedi                                             08/06/2025                                  COMEDI_TO_PHYS(3)

       Converts parameter data given in sample values (lsampl_t, between 0 and maxdata) into physical units
       (double). The parameter range represents the conversion information to use, and the parameter maxdata
       represents the maximum possible data value for the channel that the data was read. The mapping between
       physical units is linear and assumes ideal converter characteristics.

       Conversion of endpoint sample values, that is, sample values equal to 0 or maxdata, is affected by the
       Comedilib out-of-range behavior (see function comedi_set_global_oor_behavior). If the out-of-range
       behavior is set to COMEDI_OOR_NAN, endpoint values are converted to NAN. If the out-of-range behavior is
       set to COMEDI_OOR_NUMBER, the endpoint values are converted similarly to other values.

       If there is an error, NAN is returned.
