BitArShift
From Multi Theft Auto: Wiki
This functions performs an arithmetic shift on the integer value by integer n positions. In an arithmetic shift, zeros are shifted in to replace the discarded bits. In a right arithmetic shift, the sign bit is shifted in on the left, thus preserving the sign of the operand. See Bitwise operation for more details.
Syntax
int bitArShift ( int value, int n )
Required arguments
- value: The value you want to perform the arithmetic shift on.
- n: The amount of positions to shift the value by.
Returns
Returns the arithmetic shifted value as integer.

ClientThis example adds the clientside command /arshift [value] [positions = 1], which will print the result from the function bitArShift.
function getNumberAsBitString(value) if type(value) ~= 'number' then return false else local binary = '' for field = 31, 0, -1 do binary = binary .. bitExtract(value, field) if field % 4 == 0 then binary = binary ..' ' end end return binary end end addCommandHandler('arshift', function (command, value, positions) if type(value) ~= 'string' or value:len() == 0 then return outputChatBox('* Syntax: /arshift [value] [positions = 1]') end if type(positions) ~= 'string' or positions:len() == 0 then positions = 1 end local result = bitArShift(tonumber(value), tonumber(positions)) local binary = getNumberAsBitString(result) outputChatBox('* Decimal: '.. result ..', Binary: '.. binary) end )
If you trigger the command with /arshift 0xF0 4 and /arshift 0xF0 -4 you will receive as response:
* Decimal: 15, Binary: 0000 0000 0000 0000 0000 0000 0000 1111 * Decimal: 3840, Binary: 0000 0000 0000 0000 0000 1111 0000 0000
