NAME
comedi_to_phys - convert sample to physical unitsSYNOPSIS
#include <comedilib.h>
double comedi_to_phys (lsampl_t data, comedi_range * range, lsampl_t maxdata);
DESCRIPTION
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.
