 HP-35S complex numbersMessage #1 Posted by designnut on 30 Jan 2008, 9:34 p.m. When you calculate a reactance is there any way to enter it into a complex number save manual entry? Can someone point me to the routine for recovering the real and imaginary parts of a complex number in a 35S, I just have mine new. Sam Thanks.

If you want those parts in rectangular notation you will have to write a small routine. Conversion between polar and rectangular would be like this: ```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 ``` Some complex functions can be found here., following the 35s complex functions link.
