BitShiftRight

BitShiftRight[n, k] shifts the binary bits in the integer n to the right by k places, dropping bits that are shifted past the unit's position.

BitShiftRight[n] shifts one bit to the right.

Examples

Shift bits to the right by 2 positions:

BitShiftRight[20, 2]
(* 5 *)

Shift one bit to the right (equivalent to integer division by 2):

BitShiftRight[7]
(* 3 *)
