That's why I was saying you almost had to know the result was going to be complex. OK, I understand your point better now.

I suppose the problem with that method for the 34s is that you would have to have some indicator that there is a complex result stored in both the x and y register. Maybe there is a way to do that (some complex results equivalent switch). In a way the 34s does this automatically. A result of a complex operation is displayed in two lines: the real part in the lower line (7segment display) and the imaginary part above in the dot matrix display. So for ln(–2) it shows 0,693147... and above this "i 3,14159265". You can also permanently turn on the Yregisterview: the MODE menu has two special YDON and YDOFF commands for this. Dieter
