Complex number on HP 35s  Printable Version + HP Forums (https://archived.hpcalc.org/museumforum) + Forum: HP Museum Forums (https://archived.hpcalc.org/museumforum/forum1.html) + Forum: Old HP Forum Archives (https://archived.hpcalc.org/museumforum/forum2.html) + Thread: Complex number on HP 35s (/thread115913.html) 
Complex number on HP 35s  Marcel Pelletier  06072007 On the PDF data sheet we have, I remark that the HP 35s was on RPN mode whit a strange number that I think is a new way to enter a complex number on the stack. For exemple, the number (5+15i) is enter like this: enter 15 press "i" key enter 5 press "enter" key. Then you have 15i5 on the stack! So this method permit to have a whole complex number in a register. The HP 35s can now have a new COMPLEX MODE like the HP 15c!
What do you think of that?

Re: Complex number on HP 35s  Donald  06072007 Quote: I hope it's better than the 15C's: If the HP35s stack supports data types, i.e. assuming good design based on the HP28/48/50 series, the complex numbers, bittypes, and alpha prompts etc. should all be directly storeable in memory and not just stack registers. On the HP15C splitting and storing complex numbers into two registers is a pain, partitioning gets even worse when dealing with complex matrices.
Has the 35S's stack depth been mentioned yet ? It's unclear to me if the classic 4 deep stack is used or a deeper RPL like stack, or even a flag to switch between those 2 modes.
Re: Complex number on HP 35s  bill platt  06072007 I think it is quite safe to bet that: 1. There will not be an RPL kernel and no advanced "datatypes" on the stack. Perhaps they will have a complex datatype, but that will be it (for stack types). Prgrams have labels, also equations and equations as comments in same fashion (via flag) as the 32sii. 2. Stack depth is almost certainly 4 deep. This model, in addition to being celabration of the classic RPN of the 35, is also most likely to be compatible with the earlier kinthe 32sii and the 33s.
3. HP already has the 50g for the top of the line RPL, and hte 48GII for the lowercost RPL, and the 39G+ for the algebraic RPL. I don't see why they would make this machine RPLit would merely reduce its sales potential to those loking for a "scientific" rather than a graphing, and it would rob sales from the RPL models.

I didn't really want to suggest a RPL mode .. merely a dynamic depth stack option.
