• Bit operators
The bit operators B_NOT, B_AND, B_OR,
B_XOR can be used.
Operands are variables or constants of the
INTEGER type.
• Basic arithmetic operations
Real-time variables of types INTEGER and REAL
can be subjected to the basic arithmetic operations,
with each other or with a constant (+, –, *, /, DIV,
MOD).
• Mathematical functions
Mathematical functions cannot be applied to real-
time variables of data type REAL (SIN, COS,
TAN, ASIN, ACOS, ABS, TRUNC, ROUND, LN,
EXP, ATAN2, ATAN, POT, SQRT, CTAB,
CTABINV).
Example:
DO $AC_PARAM[3] = COS($AC_PARAM[1])
