Arithmetic
| Operator | Description | Example |
| + | Adds two operands. | 10 + 20 = 30 |
| − | Subtracts second operand from the first. | 10 − 20 = -10 |
| * | Multiplies both operands. | 10 * 20 = 200 |
| / | Divides numerator by de-numerator. | 10 / 20 = 2
10 / 3 = 3.333…
|
| \ [1] | Integer divides numerator by de-numerator. | 10 \ 3 = 3 |
| % | Remainder after an integer division. | 20 % 10 = 0
11 % 3 = 2
|
| [1] | The backslash is also used as an {
"rules": {
"rule": "IF 3 \\ 2 = 1 THEN switch DEVICE light TO on",
"active": 1
}
}
|
Relational
| Operator | Description | Example |
| == | Checks if the first and second (nummeric)
operand are equal.
|
20 == 10 = false
10 == 10 = true
|
| != | Checks if the first and second (nummeric)
operand are unequal.
|
20 != 10 = true
10 != 10 = false
|
| >= | Checks if the first operand is greater or
equal to the second operand.
|
20 >= 10 = true
10 >= 20 = false
10 >= 10 = true
|
| > | Checks if the first operand is greater than
the second operand.
|
20 > 10 = true
10 > 20 = false
10 > 10 = false
|
| <= | Checks if the first operand is smaller or
equal to the second operand.
|
20 <= 10 = false
10 <= 20 = true
10 <= 10 = true
|
| < | Checks if the first operand is smaller than
the second operand.
|
20 < 10 = false
10 < 20 = true
10 < 10 = false
|
New in version 8.0: ISNOT operator added
Deprecated since version 8.1.0.
| Operator | Description | Example |
| ISNOT | Checks if the first and second (character)
operand are equal.
|
a ISNOT b = true
a ISNOT a = false
|
| IS | Checks if the first and second (character)
operand are equal.
|
a IS b = false
a IS a = true
|
Logical
| Operator | Description | Example |
| AND | Checks if the first and second operands are
true.
- values greater of smaller then 0 are true
- strings equals to
0 are false- strings other than
0 are true |
1 AND 1 = true
1 AND 0 = false
foo AND false = true
true AND true = true
false AND false = true
|
| OR | Checks if the first or second operands are
true.
- values greater of smaller then 0 are true
- strings equals to
0 are false- strings other than
0 are true |
0 OR 0 = false
1 OR 0 = true
foo OR false = true
true OR true = true
false OR false = true

Other
New in version 8.1.0.

(single dot)
|
