Attention

IronPLC can only run very simple programs. The steps described are accurate but many language features are not yet supported.

Returns IN1 multiplied by IN2. MUL(a, b) is the functional form of the * operator: a * b. Both forms are equivalent.

For integer types, overflow behavior wraps around (modular arithmetic).

result := MUL(6, 7);   (* result = 42 *)
result := 6 * 7;       (* result = 42, operator form *)
