Joey Gannon Joins the Dark Side
Posted by Michael on 13 January 2004, 22:41 GMT

We are sorry to report that Joey Gannon, our hard-working file archiver, has been seen participating in the notorious RPN cult. This is the same group that is infamous for the Sliderule Massacres of '71. Oaths of secrecy prevent information from disseminating to the public, but the mystical letters RPN are rumored to stand for Really Poor Notation, though this is unconfirmed. Members have been known to do odd things in the name of Al-Gebra, their sacred way of math.

No one knows why he may have done this. One psychologist we interviewed stated, "There are many reasons why an individual would suddenly dissociate from previous beliefs." He was not of much help. Our other file archiver, Morgan, experienced no signs of mental distress, commenting: "What did Joey do!? WHAT??? He always seemed like such a good kid!"

ticalc.org readers in Maine have written to report seeing Joey dressed in black robes and performing a calculator sacrifice. His only comment was, "Oportet ministros manus lavare antequam latrinam relinquent. When I burn the calculator, my world becomes the calculator. I must go find a Voyage 200 now so that my long journey to enlightenment may begin."

Well, so much for "ticalc.org helps the earth". I'd hate to think of all the chemicals released by burning the plastic.

:(

Yeah, Neal's uber-liberal mom mentioned that as we watched it burn... perhaps I should have thought of that first. :-)

Isn't there something about "cruel and unusual punishment" and "punishing the innocent" that's aginst the law? Just think of how the poor helpless calculator felt.

The poor calc!!!!! :-( If you can't use an electronic device, at least take it apart and use the parts.

I hate RPN-it's illogical and hard to use. Isn't it Casio which is known for their RPN calcs? Or is it HP? Evil, evil, all of them...

I always saw anti-TI and pro-HP leanings in Joey. Did you see on the message boards where he kept on talking about the HP49G+? He also hates the 86 menus. >:-O

HP is known for the RPN calcs

Casio is known for the unusable calcs

Also, the 86 menus look like Casio's

But I'm not sure which came first...

What is illogical about RPN! It takes less keystrokes. I often use the RPN APP on my SE.

But... typing 3 + 5 is much closer to they way you'd write it on paper than 3 5 +, or however you'd do it. Are you sure it's less keystrokes?

Doing 3 + 5 can go either way. I find RPN extremely useful when adding large quantities of numbers.

I have used a friends calc in 7th grade and it was an old HP RPN calculator. I don't know how she could do it, but between numbers, it just looks right to have the plus sign in the middle.....for example....on a TI calculator you could do...
5 + 6 - 8*4
A lot more to do in RPN....

RPN loses out for simple stuff like this. Basically, if you have to use brackets for an expression, then RPN has the advantage.

For instance, suppose the above result needed to be divided by 2. With an RPN entry system, you'd just type [2] [/]. With algebraic entry, you'd either have to add 2 extra brackets, or manually select the last answer and divide it by 2.

As an exmple where RPN shines, try findin the sine of (e^ (sqrt (2) / 4) + 9)

[2] [sqrt] [4] [/] [e^] [9] [+] [sin] will get the result. Its a PITA to enter things like that on an algebraic calculator.

Hmm...does anyone know of any good tuitorials on RPN? I'm going to get the app that transforms my 83+ to RPN mode

You don't need tutorials for RPN. Click "(Web Page)" and read. It'll take about 10 minutes, if that.

It's very simple if you know how a stack works. Basically you call an operation on the uppermost elements of the stack... for instance
3 5 + 7 -

the interpreter adds 3 and 5 to the stack, and when it gets to + it adds the result of 5 + 3 to the stack... then it adds 7 to the stack, and calls -, adds the result of 7 - 8 to the stack. Finiding nothing else to do it returns the only element left on the stack.

basically, yes, but your use of the word 'add' so much will confuse people who don't know quite what you mean...
3+5-7= 6 strokes Algebraic
3[enter]5+7- 6 strokes RPN

what the RPN input is doing is placing 3 on the stack, that's what the first two buttons do, 5 shows 5 at the input line, then the plus adds the 3 and 5 and *replaces* the orginial 3 with an 8. Now, the 7- does about the same thing, but instead of adding it subtracts. It replaces the 8 with a 1, there is nothing left on the stack but the 1.

There, I've dumbed down your explanation enough so that anyone who takes the trouble to read it should understand what's happening :D.... now if I could only post this AC....

I suppose a computer science degree can be a bad thing when trying to explain things... :P

A simple solution is the ANS/ans(x) variable. Depends on what calculator you have.

say you wanted to do (3+5)(2+4)...10 key strokes for TI calc...3 5 + 2 4 + *...7 strokes in RPN... :)

3 enter 5 + 2 enter 4 + *

is 9 keystrokes, as opposed to 11 (you forgot the equals sign)
