HP-35S complex numbers

[designnut]

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.

You can use ARG and ABS to get the parts of a complex number in polar form. 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

Just press the "i" key, then multiply.
