This functions performs a bitwise circular right-rotation on the integer value by integer n positions. See Bitwise operation for more details.
Syntax
int bitRRotate ( int value, int n )
Required arguments
- value: The value you want to perform the rotation on.
- n: The amount of positions to rotate the value by.
Returns
Returns the circular right-rotated value as integer.
Example

ClientThis example adds the clientside command /rightrotate [value] [positions = 1], which will print the result from the function bitRRotate.
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('rightrotate',
function (command, value, positions)
if type(value) ~= 'string' or value:len() == 0 then
return outputChatBox('* Syntax: /rightrotate [value] [positions = 1]')
end
if type(positions) ~= 'string' or positions:len() == 0 then
positions = 1
end
local result = bitRRotate(tonumber(value), tonumber(positions))
local binary = getNumberAsBitString(result)
outputChatBox('* Decimal: '.. result ..', Binary: '.. binary)
end
)
If you trigger the command with /rightrotate 0xFF0000 16 you will receive as response:
* Decimal: 255, Binary: 0000 0000 0000 0000 0000 0000 1111 1111
