And since an arithmetical division ought to consider the sign, it is quite important, as which number the bit pattern is interpreted. BTW: You're just lucky that the shr-Operation you used is operating on a logical bit base and not on an arithmetical one as in CC 1.1 (which would keep the high bit as it is instead of inserting 0s).
