function type(obj: any): string
function tonumber(s: string, base: number?): number?
function tostring(obj: any): string

Tip

Second Life also adds the following:

function tovector(s: string): vector3
function toquaternion(s: string): quaternion
function torotation(s: string): quaternion
function touuid(s: string): uuid

function print(args: ...any)
function assert<T>(value: T, message: string?): T
function error(obj: any, level: number?)

function getmetatable(obj: any): table?
function setmetatable(t: table, mt: table?)

function pcall(f: function, args: ...any): (boolean, ...any)
function xpcall(f: function, e: function, args: ...any): (boolean, ...any)

function newproxy(mt: boolean?): userdata

function rawget<K, V>(t: { [K]: V }, k: K): V?
function rawset<K, V>(t: { [K] : V }, k: K, v: V)
function rawlen<K, V>(t: { [K]: V } | string): number
function rawequal(a: any, b: any): boolean

function next<K, V>(t: { [K]: V }, i: K?): (K, V)?
function select<T>(i: string, args: ...T): number
function select<T>(i: number, args: ...T): ...T
function ipairs(t: table): <iterator>
function pairs(t: table): <iterator>

Tip

Luau supports generalized iterators so you don’t need to use the ipairs and pairs functions:

for index, value in ArrayTable do
  ...
end

for key, value in DictionaryTable do
  ...
end

function unpack<V>(a: {V}, f: number?, t: number?): ...V

Equivalent to table.unpack

Removed

function gcinfo(): number
function getfenv(target: (function | number)?): table
function setfenv(target: function | number, env: table)

Danger

The above functions have been removed and are not available in Second Life SLua.
