       comedi_to_phys - convert sample to physical units


       #include <comedilib.h>

       double comedi_to_phys (lsampl_t data, comedi_range * range, lsampl_t maxdata);


       Converts 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.

       Conversion of endpoint sample values, that is, sample values equal to  0  or  maxdata,  is
       affected  by  the Comedilib out-of-range 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.
