Prior to a9e2f30 the radians were calculated as: radians = (mags == 0.0f) ? 0.0f : SDL_acosf(dotproduct(at, rotated) / mags); After that commit radians are no longer zeroed in case (mags == 0.0f), cosangle is zeroed instead, but radians are still calculated using SDL_acosf(cosangle), which results in Pi/2 in case there's no actual rotation.
