Description

Digits™ RPN Calculator

FREE until April 30, 2011!!!

Digits is a Reverse Polish Notation (RPN) calculator. It offers an infinite stack and a wide range of scientific and statistical functions.

When you hold Digits upright, you'll see a simple RPN calculator with the functions you need most of the time.

Turn Digits on its side to reveal a sliding panel of buttons for scientific and statistics functions. You can easily get to the pane you need by moving your finger along the scroll bar. This feature allows Digits to have more functions than many other calculators, while still presenting large buttons!

For those of you who are used to your legacy RPN calculator, Digits provides an intuitive interface and a similar feel. Despite the infinite stack, Digits can perform geometric and arithmetic progressions. It does this with a unique feature that we call "automatic chaining from lastX".

On top of that, Digits provides a lastY register, something that legacy users have been craving for years! It is available on the sliding button panel.

Since Digits does have an infinite stack, it's only fair that we give you a way to manipulate it. As well as providing the traditional drop and swap buttons, Digits has a stack display that allows you to move and delete items with a touch!

A detailed manual is available at http://www.goldentroutsoftware.com/Digits.html

It describes much more than what we are able to tell you here.

We hope you enjoy our product!

- NOTICE -

Digits uses IEEE double-precision arithmetic internally to ensure both accuracy and speed. The world's most popular business spreadsheet program uses it for the same reasons.

The base-10 identity bug has been fixed as of version 1.3. The input: 0.1 [Ent] 1024 [Ent] * 102 - 10 * 4 - now displays 0 as it should.

Best of many RPN calculators I've tried

:
This RPN calculator does two things right that all others I've tried have done wrong:
1. It provides audible clicks, as does the built-in Apple calculator, so you don't need earphones on an iPod to know a key press has been registered.
2. It provides huge buttons in portrait mode so you can use the calculator easily for simple calculations.

There are a bunch of other sensible features such as results that are easy to read and double clicking the C clears the registers. Finally there is an RPN calculator reliable enough and intuitive enough that I kicked Apple's calculator off my main icons page.

Not up to date, crashes more than works

:
I don't see that there's been an update on this since late 2008, which is a shame. It looks like it could be great, but the most basic operations crash the app (iPhone 3G, iOS 4). Hoping the author will update.

3/5 stars

need to be updated

:
It worked fine on my iPhone 3gs but now it crashes on my iPhone 4. Need to be updated!
