Editing WoW:Lua functions (section)

=== Bit ===
World of Warcraft includes the Lua BitLib library (which is available via "bit."), which provides access to C-style bitwise manipulation operators. It has been available since [[Patch 1.9]]. This library uses the WoW binary's native integer size. (e.g. on 32-bit builds, bit.lshift(2147483648, 1) = 0, because 1000 0000 0000 0000 0000 0000 0000 0000 -> 0000 0000 0000 0000 0000 0000 0000 0000)

''Note: Since Lua is a scripting language, using these functions to "compress" your data structures is fairly slow work. Unless you have a very large database and ''need'' to conserve RAM usage, save your information in several, individual variables.''

: [[API bit.bnot|bit.bnot]](a) - returns the one's complement of a
: [[API bit.band|bit.band]](w1,...) - returns the bitwise and of the w's
: [[API bit.bor|bit.bor]](w1,...) - returns the bitwise or of the w's
: [[API bit.bxor|bit.bxor]](w1,...) - returns the bitwise exclusive or of the w's
: [[API bit.lshift|bit.lshift]](a,b) - returns a shifted left b places
: [[API bit.rshift|bit.rshift]](a,b) - returns a shifted logically right b places
: [[API bit.arshift|bit.arshift]](a,b) - returns a shifted arithmetically right b places
: [[API bit.mod|bit.mod]](a,b) - returns the integer remainder of a divided by b
