(50g) Speed Complex entry (42s way)

[Vtile]

Hello,
Got so accustomed on the HP35s complex entry that 50g parenthesis and comma separation not to mention alpha+Rshift+6 started to feel painfull so I created these two small programs to allow automatic creation of complex number from the parts entered to the stack.

First application is independent, but the 2nd aplication/macro is calling the first one.

Code:

<< i * SWAP + >> 'Re±Im' STO

You enter in RPN: Re [SPC] Im [Re±Im]
.. and it creates a complex number representation from rectangular entry, but shown in the mode you have chosen.

Code:

<< DUP2 COS * UNROT SIN * Re±Im >> 'YɑX' STO

You enter in RPN: ABS [SPC] ARG [YɑX]
.. and it creates a complex number representation from polar entry, but shown in the mode you have chosen. Note that I haven't tested it in the radian mode almost at all, but it seems to work also in radians flawlessly (why not).

I also suggest creating a polar <-> rectangular toggler.

All bug reports and improvement suggestions are welcome.

Edit. It seems that the R→C command found in the PRG/TYPE is making only rectangular representation of the complex no matter which mode the calculator is in. Program below is using that now command for Cplx creation, else is the MODE wrapper so the type is based on the coordinate mode the calc is in (polar/rect) so you can type both polar and rect form and chose which one you need / want to enter by selecting coordination system with coordinate toggler program.

Code:

-16 FS? -15 FS? -103 FS? → Y X C
    «
  IF 'C==0' THEN
     "Not in Complex mode, Exit." MSGBOX
  ELSE
   IF 'Y==0' THEN 
      R→C // command in PRG/TYPE i just found.
   ELSE 
        IF 'X==0' THEN
           DUP2 COS * UNROT SIN *
          R→C // command in PRG/TYPE i just found.
        ELSE

      END
   END
  END

      CYCLIN

Very nice! On the second program,

Code:


<< DUP2 COS * UNROT * SIN * Re±Im >> 'XɑY' STO

I think you want

Code:


<< DUP2 COS * UNROT  SIN * Re±Im >> 'XɑY' STO

I think X and Y may be swapped (if Y is the angle)?

Y is the angle yes, it seems I made a typo last night in code. Now when you mention it, I do notice that my original naming of the polar form program doesn't follow much logic, yes I swap the X & Y to fit in stack naming style. (The code is in correct order, as it is more natural to enter ABS ARG, than ARG ABS atleast for my left to right reading OCR brains )

Indeed good catch, thx.

Yes indeed. I named your second program 'R (symbol plus/minus)(symbol theta)' to match the intent of your first program. Sorry to spell out the symbols, I don't know how to insert them here.

Both programs are now in my shortcut folder
