Example 1
print(10 or eventlog.next())
print(nil or "a")
print(nil and 10)
print(false and eventlog.next())
print(false and nil)
print(false or nil)
print(10 and 20)
Output:
10
a
nil
false
false
nil
20
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
