Type Operator Syntax Example Meaning
Arithmetic + A + B Addition: A + B
- A - B Subtraction: A minus B
* A * B Multiplication: A times B
/ A / B Division: A divided by B
^ A ^ B Raising to a power: A to the power of B (AB)
Mod A mod B Modulus: the remainder of A divided by B
Relational < A < B Less than: returns true if A is less than B
= A = B Equal to: returns true if A equal to B
> A > B Greater than: returns true if A is greater than
B
<= A <= B Less than or equal to: returns true if A is less
than or equal to B
<> A <> B Not equal to: returns true if A is not equal to
B
>= A >= B Greater than or equal to: returns true if A is
greater than or equal to B
Prefix Not NOT A Complementation: returns true if A is 0 and
False otherwise
- - A Negation (as prefix operator): returns the
negative of A
Conjunction,
Disjunction
and Inclusion
And A and B Conjunction: returns true if operands A & B
both evaluate to true. If both A and B are
integers, returns the result of a bitwise AND
operation.
Or A or B Inclusive disjunction: returns true if either
operand A or operand B evaluates to true. If
both A and B are integers, returns the result
of a bitwise OR operation.
in .. A in B..D Membership in a range: returns true if the
value of A is between B and D
in ( ) A in (B1, B2, Membership in a discrete set: returns true if
the value of A matches any of the values
