Attention

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

Returns the remainder of IN1 divided by IN2. MOD(a, b) is the functional form of the MOD operator: a MOD b. Both forms are equivalent.

The result has the same sign as IN1. The MOD function is defined only for integer types. Division by zero causes a runtime fault.

result := MOD(7, 3);    (* result = 1 *)
result := 7 MOD 3;      (* result = 1, operator form *)
result := -7 MOD 3;     (* result = -1 *)
