Logical Computation
Checks whether the two data values, e1 and e2 (e1 only for NOT), are zeros or non-zeros,
and computes according to the conditions.
AND
Logical product
(Syntax) e1ANDe2
(Condition) If the two data values e1 and e2 are both non-zeros, the computed result is 1.
Otherwise, it is 0.
(Explanation) e1 = 0, e2 = 0 → e1ANDe2 = 0
e1 ≠ 0, e2 = 0 → e1ANDe2 = 0
e1 = 0, e2 ≠ 0 → e1ANDe2 = 0
e1 ≠ 0, e2 ≠ 0 → e1ANDe2 = 1
OR
Logical sum
(Syntax) e1ORe2
(Condition) If the two data values e1 and e2 are both zeros, the computed result is 0.
Otherwise, it is 1.
(Explanation) e1 = 0, e2 = 0 → e1ORe2 = 0
e1 ≠ 0, e2 = 0 → e1ORe2 = 1
e1 = 0, e2 ≠ 0 → e1ORe2 = 1
e1 ≠ 0, e2 ≠ 0 → e1ORe2 = 1
XOR
Exclusive OR
(Syntax) e1XORe2
(Condition) If the two data values e1 and e2 are zero and non-zero or non-zero and zero,
the computed result is 1. Otherwise, it is 0.
(Explanation) e1 = 0, e2 = 0 → e1XORe2 = 0
e1 ≠ 0, e2 = 0 → e1XORe2 = 1
e1 = 0, e2 ≠ 0 → e1XORe2 = 1
e1 ≠ 0, e2 ≠ 0 → e1XORe2 = 0
NOT
Logical negation
(Syntax) NOTe1
(Condition) The result is the inverse of the status of data e1 (zero or non-zero).
(Explanation) e1 = 0 → NOTe1 = 1
e1 ≠ 0 → NOTe1 = 0
ExpressionExample
