Function bit.brshift
Shifts a number right arithmetically by a specified number of bits
Syntax	bit.brshift(number n, number bits)
Returns	number 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`÷2^bits⌋
Part of	ComputerCraft
API	bit

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
