There are multiple lua types available, which are automatically determined by the returned value of the variable, function or table.
Types
boolean | This returns a value of true or false. |
function | A function usually contains a list of actions to be executed & can often be used to calculate & return values. |
nil | If no data type is returned then whatever you queried is either empty or does not exist, thus it is nil. |
number | This usually contains an integer (whole) or floating point (decimal) number. |
string | This usually contains text or numbers wrapped in "quotation marks" or 'apostrophes'. |
table | This usually consists of an array, or multiple arrays of data & data types. |
boolean | |
---|---|
local a = true
print( a, type(a) )
|
function | |
---|---|
function a(i)
return i
end
print( a(7), type(a) )
|
nil | |
---|---|
local a = nil
print( a, " type = " .. type(a) )
print( b, " type = " .. type(b) )
|
number | |
---|---|
local a = 7
local b = 7.25
print( a, type(a) )
print( b, type(b) )
|
string | |
---|---|
local a = "hello world"
print( a, type(a) )
|
table | |
---|---|
local a = {1,1+1,1*3,2*2,20/4,"6",3.5*2,10-2}
print( a[1], a[2], a[3], a[4], a[5], a[6], a[7], a[8], type(a) )
