HP Prime complex results  Javier Goizueta  10062013 I've been playing with the HP Prime and so far I've found its arithmetic and trigonometric results to be identical to those of the classic 12digit HP calculators (HP71B, HP48,28,50, 42S, etc). But complex operations seem to differ. For example, I've tried (1, 1E12)^0.5 in the HP50G, 42S and even 35S and get the result (5.06145483078E13,1), but on the Prime I get 5.06619231322E13+i Note that when using a complex square root function instead of a generic y^x power, all the mentioned calculators yield the same accurate result for SQRT(1+i*1E12) = (5E13,1) (except for HP35S which doesn't have a complex square root).
I wonder if this difference is due to accident or is designed to be so.
