One of the eight types of Lua.
The definition of a userdata and the basic methods for accessing it
need to be written in the API. A userdata can be "full" (i.e. it can
be manipulated from Lua) or "light" (i.e. all Lua can do with it is to
determine whether two values are raw equal). These are not true
subtypes since they are treated as one type inside Lua and as two
types inside the API.
The topic is too advanced to explain any further in this Glossary.<y:LabelModel>

call a method.

Any two values can be compared for equality or inequality.
Two strings or two numbers can be compared for order.
Any other comparison is only possible with the aid of a metamethod.
Comparison operations have a higher priority than logical operations
and parentheses are seldom needed.
The result of a comparison operation is a boolean.
abc ~= nil -- True if the value of abc (of whatever type) is not nil.

The result of "not" is boolean, but the result of the other operations
is to select one of the operands.
Their action is determined by the truth of the first value.

In practice the term refers to
perhaps the most idiosyncratic feature of Lua.
When a name is not in any local scope, not even as an upvalue, Lua
looks for a key of that name in a table called _ENV which is
guaranteed always to be in scope.
The entry in _ENV with the given name is the global variable of that
name.
string -- these two notations are
_ENV.string -- equivalent
There is nothing pervasive about global variables. All their values
may be switched at the drop of a hat by simply assigning a different
table to _ENV. If that table is empty, all global variables are
instantly reset to nil.

The functions, types and data structures to be used when writing C
code that interacts with Lua.
Understanding the API requires a knowledge of C. It is therefore not
covered in this Glossary.
APIs for other languages (C++, Pascal etc) also exist, but the
official documentation (which fills half the Lua manual) is for the C
API.

A -- refers to the whole array
A[1] -- refers to a single element with key 1
Arrays in which other keys than numbers are used are called
associative arrays.
The elements of associative arrays are sometimes referred to as items.
A['name'] -- refers to a single item with key 'name'
A.name -- a synonym for A['name']
The notation A.name is only available when name is an identifier.
Both kinds of array are special cases of a table. A sequence is an
even more special case of an array.

'number' .. 3 -- the number will be coerced to a string
'3' + 10 -- the string will be coerced to a number
3.1415 * 10 -- the integer will be coerced to float
tbl = {[3.0]=true} -- the float will be coerced to integer
Coercion, especially string-to-number coercion, is considered
undesirable by many, and Lua 5.3 can be compiled with options set that
will make either or both of the first two examples illegal.

An exceptional value of type number (also written 'INF' and 'inf'),
which arises the result of overflow, division by zero etc. If you need
the notation Inf, assign such a value to the name. Inf is not a Lua
keyword, but appears in output, as does -inf.
Inf and -Inf are a legal keys in a table.
Inf can freely be used in expressions, and behaves the way one would
think it should.
Inf = 1/0
0-Inf -- -inf
Inf + 1 -- inf
Inf-Inf -- -nan
1/Inf -- 0.0
1/(-Inf) -- -0.0
Inf &lt; Inf -- false
