__NOTOC__
{{New feature/item|3.0140|1.4|5285|
This function performs a bitwise AND-conjunction on two or more (unsigned) 32-bit [[Int|integers]]. See [http://en.wikipedia.org/wiki/Bitwise_operation Bitwise operation] for more details.
}}

==Syntax==
<syntaxhighlight lang="lua">
uint bitAnd ( uint var1, uint var2, ... )
</syntaxhighlight>

===Required arguments===
*'''varN:''' The value you want to perform an AND-conjunction on

===Returns===
Returns the conjuncted value.

==Example==
<syntaxhighlight lang="lua">
local flags = 0x23 -- binary: 100011b
local mask = 0x20  -- binary: 100000b

-- Check if bit 1 is set
if bitAnd(flags, mask) ~= 0 then
    outputDebugString"Yeah. It's set"
else
    outputDebugString"I'm sorry ;("
end</syntaxhighlight>

To test if a flag is set or not it's easier using [[bitTest]].
