Description of App:
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.htmlIt describes much more than what we are able to tell you here.We hope you enjoy our product!NOTICEDigits 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.

Surprisingly accessible for an app of this nature.All the buttons appear to have labels that will make sense to the type of person likely to use this app.When used in landscape mode the function keys are in a block on the left of the screen, the numeric keys on the right. The function keys are spread over 4 pages. A 3-fingered swipe to the left or right navigates through these. However, flicking left or right button by button appeared to find all the buttons contained in the four pages without the need to actually flick from page to page.
According to its description the app usually sells for $1.99 but is free until 30 April.
