HP 35s Polar to Rectangler in Program mode Message #1 Posted by Will Hart on 5 Dec 2007, 5:24 p.m. I recently read an the message by Howard Boardman on Rectangular to polar. I tried the program. Just what I am lookin for. Does any one have s simple program mode routine to convert from Polar to Rectangler. I have been working on converting my 41cx Survey program to work on the 35s. Just need a little help. Thanks

Stack remains (otherwise) untouched and settings independent. - Pauli 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

Re: HP 35s Polar to Rectangler in Program mode Message #4 Posted by Will Hart on 6 Dec 2007, 9:02 a.m., in response to message #1 by Will Hart I have a few employees want to sit for the NCEES Surveyor in training and others going for the CST testing. The 35s was just approved in October 07. The 35s is a better choice over the 33s Thanks

Re: HP 35s Polar to Rectangler in Program mode Message #5 Posted by Howard Boardman on 6 Dec 2007, 3:35 p.m., in response to message #1 by Will Hart I've been using the following subroutines in my programs and they seem to work perfect: For R -> P LBL S x<>y i x + ARG LASTx ABS RTN For P -> R x<>y COS x<>y LASTx SIN x<>y x x<>y LASTx x RTN I didn't come up with these but they work perfectly. I still as of yet do not understand the complex number stuff with the 35s. I'm mainly doing surveying programs and if it ain't broke don't fix it!

Re: HP 35s Polar to Rectangler in Program mode Message #6 Posted by Trent Moseley on 6 Dec 2007, 10:55 p.m., in response to message #5 by Howard Boardman Howard Close but no cigar. Your R>P program (I did not check out P>R) does not give the same results of Reth's program. His routine gives the same results as the HP-32ii which has the conversions available on on the keyboard. tm

Re: HP 35s Polar to Rectangler in Program mode Message #7 Posted by Howard Boardman on 7 Dec 2007, 1:25 a.m., in response to message #6 by Trent Moseley Trent I get the same result as the 33s. All my programs with the subroutine work the same in the 35s as the 33s. Please provide an example to show me.

Re: HP 35s Polar to Rectangler in Program mode Message #8 Posted by Trent Moseley on 7 Dec 2007, 10:51 p.m., in response to message #7 by Howard Boardman Will do in the next few days. tm

Re: HP 35s Polar to Rectangler in Program mode Message #9 Posted by Trent Moseley on 11 Dec 2007, 11:22 p.m., in response to message #7 by Howard Boardman Howard- Re Rectangler to Polar (or the old ->P) I finally found the problem. Your program works just fine. The trouble I was having with your algorithm in my programs is in the stack. The HP calcs that have the simple conversion key and Reth's routine for the 35S don't lose the data in both the Z and T registers after data entry in the X and Y. I did't look into the ->R program. tm
