We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope. |

conj(z) returns the complex conjugate of the complex number z. If z is represented as x+iy where x and y are both real, conj(z) returns x-iy. Also works on a list of complex numbers.
conj(3+4i)
3-4iThe conjugate of a number $z$ is often written $\overline{z}$, and is useful because it has the property that $z\overline{z}$ and $z+\overline{z}$ are real numbers.
