Boolean operators allow you to perform logical operations. You can specify the following boolean operators in an expression:
Operator |
Meaning |
Example |
not |
Result is true if operand is false |
(not (A > B) ) |
and |
Result is true if both operands are true |
( (V1 = 5) and (V2 != 10) ) |
or |
Result is true if either or both operand(s) are true |
( (Slope < Arc) or (A <= B) ) |
With a boolean operator, you must specify boolean values as operands. Most often, these values are the results of operations involving relational operators, as shown in the examples above.
