On my Prime in Home mode I get 0.500000000001+0.866025403784*i

I have "Allow complex output from real input" checked in settings.

You are correct. I wanted to see what the Prime would do if complex output was disallowed, so I had "Allow complex output from real input" unticked. I should have made that clear. Thank you!
