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)
Hi,
The offset is for rounding to the nearest integer. Without the offset it
would round down.
