To determine the type of a variable, you can call the
type()
function, as shown in the examples
below.
The output you get from these examples may vary depending on the data format that is set.
Example: Nil
x = nil
print(x, type(x))
nil nil
Example: Boolean
y = false
print(y, type(y))
false boolean
Example: Hex constant
You can enter hexadecimal values, but to return a hexadecimal value, you must create a function, as
shown in this example. Note that hexadecimal values are handled as a number type.
hex = function (i) return "0x"..string.format("%X", i) end
print(hex(0x54|0x55))
print(hex(0x54&0x66))
Set the format to return hexadecimal values, then
OR
two hexadecimal values and
AND
two
hexadecimal values.
Output:
0x55
0x44
Example: Binary constant
Binary values are returned as floating point decimal values. Note that binary values are handled as a
number type.
x = 0b0000000011111111
y = 0B1111111100000000
print(x, type(x))
print(y, type(y))
255 number
65280 number
Example: String and number
x = "123"
print(x, type(x))
x = x + 7
print(x, type(x))
123 string
Adding a number to x forces its type to
number.
130 number
