Complex Powers & Roots on RPN-67

[Albert Chan]

RPN turned infix operator to postfix: 3 ^ 5 --> 3 5 [^]

Complex number normally expressed as (a + i*b), not (b*i + a)
We can think of [+i*] as an operator: 3 +i* 5 --> 3 5 [+i*]

It is more intuitive to input real part first, imaginery part second.
Perhaps that's why the switch over ... my 2¢
