The imaginary part of e^(i*pi) is sin(pi), resp. here sin(3,1415926...), which is approximately pi – 3,1415926... . The 12-digit machines use "pi"=3,14159265359, so the imaginary part here is ~ pi – 3,14159265359 = –2,06761537357 E–13. In the same way a 10-digit calculator should return pi – 3,141592654 = –4,102067615 E–10. But since most of these calculators internally use 13 digits for pi I'd expect not more than –4,10 E–10. Dieter Edit: corrected the value for 10-digit devices |
