Lars,

Looking at the macro IIO_DEGREE_TO_RAD() to translate degree/s into rad/s, I
don't understand why we add an offset when doing the conversion:

#define IIO_DEGREE_TO_RAD(deg) (((deg) * 314159ULL + 9000000ULL) / 18000000ULL)

Shouldn't it just be
#define IIO_DEGREE_TO_RAD(deg) (((deg) * 314159ULL) / 18000000ULL)

Gwendal.
