a - b	Subtraction
a * b	Multiplication
a / b	Division
a % b	Modulo (remainder)
a ^ b	Exponent (power)

Comparison operators

Syntax	Meaning
a < b	Less than
a > b	Greater than
a <= b	Less or equal
a >= b	Greater or equal
a == b	Equal
a != b	Not equal

---

Logical operators

Syntax	Meaning	Example
a && b , a and b	Logical and True if both are true	(a>b) and (c>d)#a=Temp;b=Max;c=Pressure;d=Min
`a		b/a or b`

Comparison and logical operators return a discrete value of either true or false, except when either input is null. In that case a value of null is returned.

If the return value is assigned to an analog Tag, the assigned values are either 1 (true), 0 (false) or null.
