HP Prime complex results - Printable Version +- HP Forums (https://archived.hpcalc.org/museumforum) +-- Forum: HP Museum Forums (https://archived.hpcalc.org/museumforum/forum-1.html) +--- Forum: Old HP Forum Archives (https://archived.hpcalc.org/museumforum/forum-2.html) +--- Thread: HP Prime complex results (/thread-252298.html) HP Prime complex results - Javier Goizueta - 10-06-2013 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 12-digit HP calculators (HP-71B, HP-48,28,50, 42S, etc). But complex operations seem to differ. For example, I've tried (-1, 1E-12)^0.5 in the HP50G, 42S and even 35S and get the result (5.06145483078E-13,1), but on the Prime I get 5.06619231322E-13+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*1E-12) = (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.
