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.
