## Operators

The operators below are listed in order of decreasing precedence.
The evaluation of an expression begins with the highest precedence operator and from left to right.

### Arithmetical Operators

 ^ (or **) Power of precedence 2 * Multiplication precedence 3 / Division precedence 3 MOD (or %) Modulo (remainder of division) x MOD y = x – y * INT (x/y) precedence 3 + Addition precedence 4 - Subtraction precedence 4

### Note

+ (addition) can also be applied to string expressions: the result is the concatenation of the strings.
The result of the ‘/’ (Division) is always a real number, while the result of the other operations depends on the type of the operands:
if all operands are integer, the result will be integer, otherwise real.

### Relational Operators

 = Equal precedence 5 < Less than precedence 5 > Greater than precedence 5 <= Less than or equal precedence 5 >= Greater than or equal precedence 5 <> (or #) Not equal precedence 5

### Note

These operators can be used between any two string expressions also (string comparison is case sensitive).
The result is an integer, 1 or 0.
There is not recommended to use the ‘=’ (Equal), ‘<=’ (Less than or equal), ‘>=’ (Greater than or equal),
‘<>’ (or #) (Not equal) operators with real operands, as these operations can result in precision problems.

### Boolean Operators

 AND (or &) Logical and precedence 6 OR (or |) Logical inclusive or precedence 7 EXOR (or @) Logical exclusive or precedence 8

### Note

Boolean operators work with integer numbers.
In consequence, 0 means false, while any other number means true.
The value of a logical expression is also integer, i.e., 1 for true and 0 for false.
It is not recommended to use boolean operators with real operands, as these operations can result in precision problems.
