NAME

6       comedi_to_physical - convert sample to physical units using polynomials
7

SYNOPSIS

9       #include <comedilib.h>
10
11       double comedi_to_physical(lsampl_t data,
12                                 const comedi_polynomial_t * conversion_polynomial);
13

DESCRIPTION

15       Converts data given in Comedi's integer sample values (lsampl_t,
16       between 0 and maxdata) into physical units (double). The
17       conversion_polynomial parameter is obtained from either
18       comedi_get_hardcal_converter or comedi_get_softcal_converter. No range
19       checking of the input data is performed. It is up to you to check for
20       data values of 0 or maxdata if you want to detect possibly out-of-range
21       readings.
22

RETURN VALUE

24       Physical value corresponding to the input sample value.
