Bitwise Logical Operators
~ Bitwise
complement Integer-integer Integer ~0b11111110 = 0b00000001
& Bitwise AND Integer-integer Integer 0b11111110 & 0b01010101 = 0b01010100
^
Bitwise exclusive
OR Integer-integer Integer
0b11111110 ^ 0b01010101 = 0b10101011
|
Bitwise inclusive
OR Integer-integer Integer
0b11111110 | 0b01010101 = 0b11111111
Shift Operators
<<
Left shift Integer-integer Integer
0b11111110 << 3 = 0b11110000
>> Right shift Integer-integer Integer 0b11111110 >> 1 = 0b01111111
Assignment Operators
=
Assignment Any Any
A = 1
B = C = A
+=
Addition
assignment Integer-integer Integer
x = 1
x += 1 = 2
String-string String
a = "one "
a += "two" = "one two"
Raw byte-raw byte Raw
z = '001122'
z += '334455' = '001122334455'
List-list List
x = [1, 2]
x += [3, 4] = [1, 2, 3, 4]
Integer-list List
y = 1
y += [2, 3] = [1, 2, 3]
Integer-string String a = "number = "
a += 2 = "number = 2"
*Note: integer-string concatenation uses decimal
conversion.
String-list List
s = "one"
s + ["two"] = ["one", "two"]
-=
Subtraction
assignment Integer-integer Integer
y = 3
y –= 1 = 2
*=
Multiplication
assignment Integer-integer Integer
x = 3
x *= 1 = 3
/= Division
assignment Integer-integer Integer s = 3
s /= 1 = 3
%= Modulus
assignment Integer-integer Integer y = 3
y %= 1 = 0
>>= Right shift
assignment Integer-integer Integer b = 0b11111110
b >>= 1 = 0b01111111
<<= Left shift
assignment Integer-integer Integer a = 0b11111110
a <<= 3 = 0b11111110000
