Example 2

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 3

hex = function (i) return "0x"..string.format("%X", i) end

a, b = 0b01010100, 0b01100110

print(hex(a), "&", hex(b), "=", hex(a & b))

Set the format to return hexadecimal values, define binary values for a and b, then AND a and b.

Output:

0x54 & 0x66 = 0x44

String concatenation

String operators

Operator Description

Concatenates two strings. If either argument is a number, it is coerced to a string

(in a reasonable format) before concatenation.

Example: Concatenation

print(2 .. 3)

print("Hello " .. "World")

Output:

Hello World

• ^ (exponentiation)

• not, - (unary), ! (logical NOT)

• *, /, <<, >>

• +, –, &, |, ^^

• .. (concatenation)

• <, >, <=, >=, ~=, !=, ==
