a &= 0b01010101 = 0b01010100
^=
Bitwise
exclusive OR
assignment
Integer-integer
Integer
e = 0b11111110
e ^= 0b01010101 = 0b10101011
|=
Bitwise
inclusive OR
assignment
Integer-integer
Integer
i = 0b11111110
i |= 0b01010101 = 0b11111111
List Operators
sizeof()
Number of
elements
Any
Integer
sizeof([1, 2, 3]) = 3
sizeof('0011223344') = 5
sizeof("string") = 6
sizeof(12) = 1
sizeof([1, [2, 3]]) = 2
*Note: the last example demonstrates that the
sizeof()
operator returns the shallow count of a
complex list.
head()
Head
List
Any
head([1, 2, 3]) = 1
*Note: the Head of a list is the first item in the list.
tail()
Tail
List
