This program can convert rectangular coordinates to polar and polar to rectangular, giving both output values simultaneously. The calculation will automatically show the radical form of the R value when you convert from Polar to Rect, and automatically divide the R value by pi when in Radians mode.

The program can switch between Degrees and Radians (so you don't have to exit the program). It automatically sets up the editor with the lists RX, RY, PR, Pθ (theta), and PF, storing previous conversion results in consecutive order even after you exit the program.

PF is list for coefficient of pi so it might be easier to read if pi was multiplied by a fraction or rational value; if in degree mode, the stored value is 0 (zero).

The "PIWIZ" is nothing other than the A or a program created by another user, so I take no credit for it. The only difference here is that it can be used on an X, Y, R, or θ value of the most recent calculation in case the irrational representation was too confusing.

Finally, the clear option clears all five lists.

Since no coloring is used, it should work for TI-84 models that are not CE, but the output settings may need to be changed for read-ability
