The answer shown by the application is wrong. I unchecked Pretty Print, copied the output to Notepad++, deleted all (xxx digits) and spaces, replaced i by I and finally copied that to gp. All five roots shown are nonreal, so something is not good.
Another error is that the digits in group is not working. The program always shows groups of 6 digits.
I will work on that.
