An innovative RPN and stack-calculator with keyboard input (as chrome extension)

Description from store
Mouseless Stack-Calculator is a innovative calculator and currency converter with fast keyboard entry. It has two modes: an RPN-mode and a stack-mode. The well known RPN stands for Reverse Polish Notation and it saves you time as it avoids the use of parenthesis. The only catch is that the entry of data is a bit different to what most people expect, so you have to learn to work with it. The stack-mode of this calculator is new. It's a bit similar to RPN in the way that is also uses a stack an avoids the use of parenthesis. But it's unique in the way that it has no reversed data entry but follows the 'normal' sequence. All calculations can be done by use of the keyboard, so no time consuming mouse clicks. It can handle both real and complex numbers and supports different notations. Mouse Stack-Calculator is available as Chrome extension, as desktop app and can run in a webbrowser window.

Latest reviews
- (2017-09-13) Jeff Martens: Doesn't do RPN.
- (2016-10-02) Steve: Didn't think I would like it, but I like it a lot!
- (2016-05-27) Ethan Davey: it sucks
- (2016-03-01) Frank O'Brien: thought I'd only like an HP type RPN, but this keyboard interface is better than trying to tap buttons, and it shows some history to catch any entry errors. It's excellent for quick math, and trig functions. For financial or more complex stuff, I use a spreadsheet, but there's many times where you want a quick calculator available in your browser corner.
- (2015-11-15) Wow, this calculator rocks!
- (2015-05-23) Jorge Fonseca: RPN mode is fantastic, very good with my Chromebook, the keyboard data entry is very clever.
- (2015-02-19) Christophe Kaempfer: utile et bien... certaines fonctions pourrait encore être simplifiés et le "look" amélioré...
- (2014-09-14) Buddy Whittenburg: Great RPN calculator that works in the chrome ecosystem. It also has a non-RPN mode, but I prefer RPN. This app is really well thought out from a pure usability standpoint. Once you get the key commands worked out it will be your go-to quick calculator
- (2014-08-14) Shelby Cain: In the past I would have given this extension 5 stars. However, the latest version wants access to all data on all web sites and that is simply unacceptable. Uninstalling and moving on.
- (2014-08-14) Jerry Morrison: I liked this a lot but the latest version wants access to my data on all web sites. No way.
- (2014-06-28) Jes.e B.: Finally!! A useful RPN calculator for the Chrome environment. I'm rather amazed that instead of typing "sin" you can do this through a menu and key abbreviations. Very, very, very, slick. Would give it five stars if only it used floating decimal representation for numbers instead of the (industry standard floating binary). What this means is that only .5, .25, .125, etc. can be represented perfectly. To see the problem, try "9 8.7 - .3 -", the answer is actually zero which a three dollar calculator from the grocery store will give you. And no. Please don't "fix" it by putting a rounding operation before you display. Please don't. Leave it this way rather than rounding. That way leads to madness.. ;^} I do know the arithmetic library is a generally non-solvable problem, unless you use a language where you can actually specify the data storage format for numbers (Cobol, Fortran, Ada..) which modern languages lack, or you use a library for BCD or something which is not part of any standards. Again, despite my gripes, Thank you for the really fantastic calculator app!
- (2014-06-03) John S Wolter: Just installed it & tried some calculations I was working. It has a good keyboard feel to it. Works as expected & seems to have a short learning curve. Easy to put to work on a practical project.
- (2014-02-28) Alan W: This is now my favorite calculator!
- (2014-02-26) Daniel Kirkham: Excellent calculator! This calc can be used with just the keyboard and has robust RPN support. My only complaint is that it does not have good ChromeOS integration. It would be nice if I could unpin it from my browser toolbar and instead have it on my ChromeOS taskbar.
- (2013-08-09) Robert M. Papillion: Very nice implementation of RPN. Very, very speedy. I love the fact that it wasn't designed for mouse usage and then awkwardly adapted for occasional keyboard usage.
- (2013-03-10) Jeremy Gibbs: I always forget to come back and review, so I will give it 5 stars for the few minute test I gave it. Seems like it has all the basic things I wanted to simulate the HP 48G I used to use. (Also, to Android users: try RealCalc app)
- (2013-02-07) Ken N: Very nice, I use it all the time.
- (2011-12-15) Robert Ritter: Exactly what I needed. The best RPN calculator I've used, better than my HP. Thank you.
- (2011-12-05) Nathan Lassig: Oh man! It is so sad to see only eight reviews on here. This is an amazing calculator. For speedy calculations it is probably the greatest calculator I've ever seen. It beats both handhelds and advanced software (like Mathematica, Maple, and Matlab) by combining the best elements of both. It combines the speed of keyboard entry with the simple commands of a handheld. The only challenge is that it's a steep learning curve, but it's made easier by the constant presence of explanatory instructions. I'd love to see this as a standalone program. I'd also love to see more features. Thanks so much for this amazing calculator.
