{{New feature/item|3.0132|1.3.2|5340|
This function performs an AND-conjunction on two or more (unsigned) 32-bit [[Int|integers]] and checks, whether the conjuncted value is zero or not. See [http://en.wikipedia.org/wiki/Bitwise_operation#AND Bitwise operation] for more details.

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

===Required arguments===
*'''varN:''' The value you want to perform the operation on (see above)

===Returns===
Returns ''true'' if the conjuncted value is '''not''' zero, ''false'' otherwise. If a bad argument was passed to [[bitTest]], you'll get ''nil''.

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

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