If you want a proper scientific calculator, why not try some of the emulators about? I use an HP42S on my Windows, Linux, Mac and Android devices.
Free42 : An HP-42S Calculator Simulator

Great post

That takes me back to the first HP-35 in 1972. It used Reversed Polish Notation. Very few companies produced RPN calculators after that. It took me 25 years to stop looking for the "Enter" button on other types of calculator (algebraic?). Pushing and popping on the stack made complex calcs very simple, so no parentheses were required. Cost $395. I didn't pay - RR paid.

This post prompted me to look on the iPhone. I found an HP-35 simulator. Cost £1-99. Brilliant. It even has a "click" to emulate the keypress. It was the click that made the HP-35 feel like a Rolls Royce compared with its competitor from Texas Instruments.

The User Manual is here:
http://www.cs.columbia.edu/~sedwards/hp35colr.pdf

Trivia: The User Manual taught me one of the most accurate approximations for "pi" that I've ever seen: 355/113

The mnemonic is: 11 33 55. In other words, write 113. Then write 355 above that.

Here is the quote from the User Manual regarding the accuracy: 355/113 approximates pi to within 8.47 millionths of one percent. (It makes 22/7 look pretty sad.)

Thanks again for the HP-42S post

I can remember a Mathematics teacher setting a project for us, his students to calculate Pi to an many places as we could - I think he expected a maximum of ten to fifteen places. Of course we had access to the school Manframe, and a mischievous nature

- So we got the Mainframe to calculate Pi to one hundred decimal places and copied it out longhand and handed it in when due - I believe it took him several days to manually calculate to check we were correct

These days High accuracy Pi figures are just a google away ...

100,000 Digits of Pi

Our mischievous antics did cause some problems like the time we removed all the fixing screws from the partition wall between two temporary classrooms

or connected all the piping feeding the Bunsen burners in the Chem lab to the cold water main

I thought Pi had only 50,000 digits. Now I'm going to have to memorize the other 50,000. That's my afternoon and most of the evening ruined.

That doesn't surprise me in the slightest.

I did a contract with Technicolor in Cwmbran. So I know all about the mayhem and vandalism of the Viet Gwent

Hi folks

as a Phd in Engineering (Electrical) I can honestly say there hasn't been anything the new windows calculator can't do that I've needed. That said I prefer the look of the older one but that's just cosmetic and usually if I'm using a calculator I find doing it on a Samsung smart phone is far easier than messing around in windows unless I have to cut and paste result into spreadsheet etc.

Cheers

In my opinion, one certainly can't claim to have used a calculator in anger, if they have never used RPN :)

@jimbo45

I have actually purchased a Scientific calculator for my Android phones and tablets

https://play.google.com/store/apps/d...lCalc&hl=en_GB (but I still have one in my Bag and my desk drawer )
@Golden The pro version that I have even has RPN to keep old timers happy

Nice @Barman58l....BTW, the HP42S can be found on Play store too. Works brilliantly on Android, and completely free too (no ads) if its ever of interest.
