{{fbdoc item="title" value="Bitwise Operators Truth Tables"}}----
Computed values for the bitwise logical operators.

**{{anchor name="BINARY|Binary operators"}}**
Operators that take two operands.
**{{anchor name="UNARY|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, (##[[KeyPgOpNot|Operator Not]]##), the logic is applied to its right-hand side operand only.

=={{fbdoc item="keyword" value="KeyPgOpAnd|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.

=={{fbdoc item="keyword" value="KeyPgOpEqv|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.

=={{fbdoc item="keyword" value="KeyPgOpImp|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.

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

=={{fbdoc item="keyword" value="KeyPgOpXor|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.

{{anchor name="UNARY"}}{{fbdoc item="section" value="Unary operators"}}

=={{fbdoc item="keyword" value="KeyPgOpNot|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.
