Examples: Bitwise operators
For these examples, tag1 = 5 (binary 0000 0000 0000 0101) and
tag2 = 2 (binary 0000 0000 0000 0010)
tag1 & tag2
Returns 0 (binary 0000 0000 0000 0000).
tag1 | tag2
Returns 7 (binary 0000 0000 0000 0111).
tag1 ^ tag2
Returns 7 (binary 0000 0000 0000 0111).
tag1 >> 1
Returns 2 (binary 0000 0000 0000 0010).
tag1 << 1
Returns 10 (binary 0000 0000 0000 1010).
~ tag1
Returns -6 (binary 1111 1111 1111 1010).
Evaluation order of operators
Expressions with more than one operator are evaluated in this order:
 Operators in parentheses are evaluated first.
Therefore, to change the order of precedence, use parentheses.
 The operator with the highest precedence is evaluated next.
 When two operators have equal precedence, they are evaluated from left to right.
