->P will calculate the square root of the sum of squares in the numerator and ->R will calculate the arctangent of the ratio.

- Pauli

So, Pauli, If I were to use this formula correctly, what are the inputs for the ->P and ->R operations? It seems obvious, but to avoid mistakes, how should I interpret the X and Y registers for both ->P and ->R operations? Thanks.
