Meaning
Addition
Subtraction
Multiplication
● Division in synchronized actions: INT / INT ⇒ INT
● Division in synchronized actions with REAL result by using the function ITOR():
ITOR( INT ) / ITOR( INT ) ⇒ REAL
● Division in NC programs: INT / INT ⇒ REAL
Integer division: INT / INT ⇒ INT
Modulo division (only for type INT) supplies remainder of an INT division
Example: 3 MOD 4 = 3
Meaning
Equal to
Not equal to
