Vey handy utility

A Google User

Very ugly, but very useful. I'd like to see it look more like a real calculator. Being able to customize the button layout would be a nice addition.

## Scientific RPN calculator

Laurent Rodier

1

Listen Read Device Only Added Installed My RPN calculator is a scientific and financial calculator inspired by the Hewlett-Packard HP-10C series pocket calculators of the 80s, most notably the HP 11C and HP 15C models.

These software version has borrowed the RPN (Reverse Polish Notation) and the look&feel of those calculators. It features classical 4 operations, logarithms, trigonometry, statistics, and macros for easy programming. It also features complete support for complex numbers along with 2nd, 3rd, and 4th degree equations solving.

Its unique magenta L key allows switching from one layout to another, thus saving space on small displays like smartphones without compromising usability.

Support for gestures allows switching from one keyboard to another by swiping left or right, and a light swipe up or down on a key executes the associated f or g function, without any need to actually press the f or g key.

See the web pages of the application at http://calc.lsrodier.net for complete keys description and samples.

My RPN calculator is compatible with all devices running Android 2.1 and up and supports both horizontal and vertical orientations. It does however requires a device with a minimum screen resolution of 320x480 (or 480x320 according to orientation). Note that tablet screens 1280x800 are properly managed.

Summary of the main functions:

* RPN input

* Portrait/landscape and multi-resolution layouts

* Gesture support for extended/simplified inputs

* Arithmetic functions (+, -, x, /, 1/x, +/-, etc)

* Trigonometry, logarithms, hyperbolic trigonometry

* Percentages (+, -, variation, total)

* Dates

* Complete complex numbers support

* 2nd, 3rd, and 4th grade equations solving

* Unit conversions (temperatures, distances, etc)

* Macros for simple programming tasks

Summary of the main statistical functions:

* 1- and 2-variable statistics

* Sums (Σx, Σx2, Σy, Σy2, Σxy)

* Mean, weighted mean, standard deviation

* Linear regression

* Correlation coefficient

* Linear estimation

* Statistical registers table

Listen Read Device Only Added Installed Easy-to-use calculator for simple mathematical operations using powerful Reverse Polish Notation (RPN), like HP calculators as HP-48 series or HP-12C.

This app is ad-supported (that's the only purpose for which network access permission is used). If you prefer, a Premium version is also available with some additional buttons, no ads and no network access permission necessary.

Instructions

=========

The stack

----------------

When you type a number and press Enter, the number is stored in the lowest position of the stack, marked by 1:

If you type another number and press Enter, the second number takes the lowest position, and the first number is pushed to position 2: (if you just press Enter without typing a new number, the first number is duplicated).

You can store up to 50 numbers in the stack, even though the screen only shows the numbers on the 4 lowest positions (1: to 4:)

If you press the Down arrow, the number in the lowest position in the stack is erased, and the others are popped one position down.

Press C to cancel the number while you are typing. Press C again to clear the stack.

Mathematical operations

-----------------------------------

If you press one of the mathematical symbols (+,-,x,÷), the corresponding operation is executed using as operands the two numbers in the lowest positions of the stack.

If you press one of the mathematical symbols while typing a number, the operation is executed between the number in the lowest position of the stack and the number that you are currently typing.

The ± key will change the sign of the number that you are currently typing or that of the number in the lowest position of the stack otherwise.

Example

--------------

If you want to compute the operation 2 x (8 - 5) do as follows:

- Type 8 and Enter

- Type 5 (followed optionally by Enter) and -

(You can also sum -5 doing: 5, ±, +)

- The lowest position of the stack shows the partial result (3)

- Type 2 and x (or 2, Enter, x)

- The final result (6) is shown on the bottom of the stack

Listen Read Device Only Added Installed Clean RPN is a simple and clean RPN calculator. Unlike other RPN calculators which try and mimic the appearance 30 year old desk calculators, clean RPN takes advantage of the screen space and rich input that your phone or tablet provides. The results of your calculation appear while you type and a scrollable list of previous calculations allows you to easily keep track of your history.

Features:

• Perform calculations using RPN - Reverse Polish notation AKA postfix notation

• Results appear as you type your calculation - no need to press enter

• Scroll through a list of history

• Tap on a result from your history to include it in the current calculation

• Support for tablets and phones

• Share your history via e-mail, etc

• Use custom number and function key boards to build your calculation - or your devices built in keyboard

• Wide number of mathematical functions supported

Listen Read Device Only Added Installed ## RPN Converter

Paweł Maślak

1

Listen Read Device Only Added Installed RPN Converter is a very handy mathematical tool - a converter from Reverse Polish Notation(postfix notation/ONP) to standard infix notation and the other way round.

The input expression can be entered with both numbers and symbols, the latter of which may be interpreted as either function symbols, when the word is three letters long, or values, in other cases. E.g the expression "sin(x)" will be interpreted as the value of the function sin for value x, Meanwhile "abcd+cd" will be interpreted as a sum of two values symbolized by abcd and cd.

The application takes into acount the unar operator "-" as well as multiplication operator ommission in cases when the context is clear.

Listen Read Device Only Added Installed This is a simple RPN (Reverse Polish Notation) calculator designed for basic mathematical calculations. It is designed to replace the four function algebraic calculator found on android phones. The calculator display shows the top four values on the stack (X, Y, Z, and T for those familiar with HP calculator terminology), and holds up to 46 more. In addition to the add, subtract, divide, and multiply functions, the calculator also includes a square root and power function.

Listen Read Device Only Added Installed ## RPN Vector Calculator

GE Measurement & Control Solutions

1

Listen Read Device Only Added Installed The vector calculator is designed to assist with typical vector operations that are used when working with rotating machinery vibration measurements.

Vector calculations are commonly used for machinery diagnostics as well as routine work such as rotor balancing. This calculator is designed specifically to support rotating machinery vibration conventions.

Data can be entered in “amplitude and phase lag,” or “Cartesian coordinates.” Phase lag values between 0 and 359 degrees allows you to enter and calculate vectors without the need to convert from a pure mathematical coordinate convention (0 to 180 degrees).

This calculator uses Reverse Polish Notation (RPN) convention. It is effective for carrying out multiple calculations using the results from previous or sub calculations to continue.

Values are entered into the “stack” and the operation is then performed.
