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

EXPT¶

Returns the result of raising a base to an exponent.

Returns IN1 raised to the power IN2. EXPT(a, b) computes a^b. For integer types, the exponent must be non-negative. The operator form is **.

result := EXPT(2, 10);       (* result = 1024 *)
value := 3 ** 4;             (* value = 81, operator form *)
