I think the rounding issue may come from the y^x. I tried this simple example with (1+i)^2:
1, ENTER, 1, 0, ENTER, 2, CPX, Y^X = (-7,5998)^-39 + 2i
1, ENTER, 1, CPX, X^2 = 2i
In both cases the 15c and 42s give 2i as the result, either with y^x or x^2.
I tried the RM command (thanks for calling me geek :-))and it did not make any difference.
As you say, it is close enough to zero.
