NAME

       comedi_to_physical - convert sample to physical units using polynomials

SYNOPSIS

       #include <comedilib.h>

       double comedi_to_physical(lsampl_t data,
                                 const comedi_polynomial_t * conversion_polynomial);

DESCRIPTION

       Converts data given in Comedi's integer sample values (lsampl_t, between 0 and maxdata)
       into physical units (double). The conversion_polynomial parameter is obtained from either
       comedi_get_hardcal_converter or comedi_get_softcal_converter. No range checking of the
       input data is performed. It is up to you to check for data values of 0 or maxdata if you
       want to detect possibly out-of-range readings.

RETURN VALUE

       Physical value corresponding to the input sample value.
