Computed values for the bitwise logical operators.

Binary operators Operators that take two operands.

Unary operator Operator that take a single operand.

These logical operators return a value based on the value of their operand(s). For the binary operators, each bit in the left-hand side value is applied logically to the corresponding bit in the right-hand side value. The result of this operation is returned. For the unary operator, (Operator Not), the logic is applied to its right-hand side operand only.

Binary operators

Operator And (Conjunction)

Bits in the result are set if and only if both of the corresponding bits in the left and right-hand side operands are set.

Lhs	0	0	1	1
Rhs	0	1	0	1
Result	0	0	0	1

Operator Eqv (Equivalence)

Bits in the result are set if and only if both of the corresponding bits in the left and right-hand side operands are both either set or unset.

Lhs	0	0	1	1
Rhs	0	1	0	1
Result	1	0	0	1

Operator Imp (Implication)

Bits in the result are set if and only if the corresponding bit in the left-hand side operand implies the bit in the right-hand side operand.

Lhs	0	0	1	1
Rhs	0	1	0	1
Result	1	1	0	1

Operator Or (Inclusive Disjunction)

Bits in the result are set if either of the corresponding bits in the left and right-hand side operands are set.

Lhs	0	0	1	1
Rhs	0	1	0	1
Result	0	1	1	1

Operator Xor (Exclusive Disjunction)

Bits in the result are set if and only if one of the corresponding bits in the left and right-hand side operands is set.

Lhs	0	0	1	1
Rhs	0	1	0	1
Result	0	1	1	0

Unary operators

Operator Not (Complement)

Bits in the result are set if the corresponding bits in the right-hand side operand are unset, and unset if they are set.

Rhs	0	1
Result	1	0
