| Feb 12, 2016 at 16:44 | comment | added | N. S. | @user51189 no, $i$ is not an integer. It is a complex number which is neither real, nor integer nor rational. | |

| Feb 12, 2016 at 16:40 | comment | added | Gyro Gearloose | Look at en.wikipedia.org/wiki/Field_extension for better understanding. $\mathbb C$ is isomorphic to $\mathbb R[X]/(X^2+1)$. (And be warned, this is a big thing, don't be frustrated if you don't getunderstanding in 10 minutes). | |

| Feb 12, 2016 at 16:39 | comment | added | Thomas Andrews | No, it is not an integer, nor a real number. It is a "complex number." It is something called an "algebraic integer," but that is not the same as being an integer. $\sqrt{2}$ is an algebraic integer, for example, but it is not an integer. Similarly, there is a class of numbers called "Gaussian integers," and $i$ is a Gaussian integer, but again, not an integer. | |

| Feb 12, 2016 at 16:36 | comment | added | N. S. | $i$ is just a number and should be treated as any other numbers. | |
