Re: hp 20s Message #7 Posted by Bill Platt on 14 Mar 2003, 5:54 p.m., in response to message #6 by hugh
I just bought 4 20s's from a store recently, and when I showed them to a co-worker, he immediately bought one! Nice (for an Algebraic)!
Being an RPL fanatic, I did some little toy program writing and found that indeed, the keystroke difference between the 32sii (or any RPN) and the 20s is significant in almost all cases. Typically it seems to be at least 10% more lines, and sometimes double (try converting feet,inches,eights to decimal feet):
RPN:
Load stack:
z feet
y inches
x eighths
LBL A
8
/
+
12
/
+
RTN
ALgebraic----a lot longer!! (I leave it to the imagination--a challenge to see if anyone can equal or beat that with the algebraic....
But, the Algebraic can nest deeper than a 4 level stack (but why would you want to--always better to solve from "inside out" anyway!!)
I will put that grain out again here----TIME for a NEW RPN MAKER!
