RE: Euler Identity in Home
Hmm...

I'm surprised by the size of the approximation, and also observe that other traditional approximations (on other, ancient non-HP calculators) tend to make their presence felt with basic trig like sin(90) etc, which are caught on HP calcs.

On an old (semi-notorious National Semiconductor) RPN calculator sin(90) yields 0.999999999997 or thereabouts, leading to much amusement amongst rich HP owners.

I wonder what other e^ix capable HPs yield -- does the 50/38/39 yield a similar answer?
