{{Function |name=bit.brshift |args=int n, int bits |api=bit |returns=int the value of n shifted right by bits bits, with the shifted-in bits being equal to the original number’s 31st bit, which is equivalent to ⌊n÷2bits⌋ |addon=ComputerCraft |desc=Shifts a number right arithmetically by a specified number of bits |examples=
 Example | |
| Shift the number 73 (1001001) right by 2 bits, yielding 18 (10010) | |
| Code |
print(bit.brshift(73, 2)) |
| Output | 18 |
| Example | |
| Shift the number 2,147,483,648 (10000000000000000000000000000000) right by 2 bits, yielding 3,758,096,384 (11100000000000000000000000000000) | |
| Code |
print(bit.brshift(2147483648, 2)) |
| Output | 3758096384 |
