For a long article on rectangular to polar conversions look at this discussion. By the end, the programs for doing the conversion were pretty good. I've submitted the "best" to the museum for inclusion in the software library. I've also included them here:

P001 LBL P
P002 FS? 10
P003 GTO P011
P004* Rv
P005 Rv
P006 eqn REGZ+i*REGT
P007 ARG
P008 LASTx
P009 ABS
P010 RTN
P011* CF 10
P012 XEQ P004
P013 SF 10
P014 RTN
R001 LBL R
R002 FS? 10
R003 GTO R012
R004* Rv
R005 Rv
R006 eqn [REGZ*SIN(REGT),REGZ*COS(REGT)]
R007 [1,0]
R008 x<>y
R009 *
R010 EQN LASTx*[0,1]
R011 RTN
R012* CF 10
R013 XEQ R004
R014 SF 10
R015 RTN

Both routines preserve the Z and T registers and return their results in the X and Y registers. The are also independent of the settings on the calculator and honour the current trig mode.

- Pauli

and in particular the asterix symbol (*) in a number of the lines. Could someone maybe explain to me how this is inputed and what it means?
