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.
1.30 number
Example: Function
function add_two(first_value,
second_value)
return first_value + second_value
end
print(add_two(3, 4), type(add_two))
7 function
Example: Table
atable = {1, 2, 3, 4}
print(atable, type(atable))
print(atable[1])
print(atable[4])
Defines a table with four numeric
elements.
Note that the "table" value (shown here
as a096cd30) will vary.
table: a096cd30 table
