double comedi_to_physical (lsampl_t data, const comedi_polynomial_t *conversion_polynomial);
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.
This function is intended to supplant comedi_to_phys(), and was introduced in order to support software calibrations.
Physical value corresponding to the input sample value.
