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)
* 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
It can perform numerical integration and solve the roots of equations in addition to supporting complex numbers and matrix calculations.

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.
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.
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

And now through this emulator for the HP-35, where both perfectly emulates the LED screen of the original 15-digit calculator physically and how we can make use of it in a virtual like you're actually physically in our hands through our Android device.
The HP-35 calculated arithmetic functions, logarithmic and trigonometric functions.
Some historical curiosities of this calculator are:
- The display of 15 characters in the HP 35, when the reverse was seen, could produce a limited number of alphabetic messages. For example, 710.77345 would read as "SHELL OIL". The sample was probably more extravagant +40 57738.57734 E would be read as "Oh Hells Bells".
- The HP 35 was just 5.8 inches long and 3.2 inches wide. This was the pocket size of William Hewlett, of there as the "pocket calculator".
- The power requirement of the LED display was responsible for the short life between battery charges the HP 35, about three hours. To prolong the operating time and prevent damage from overuse of the slide switch on / off, users could press the decimal point key to force the display to illuminate only a segment of the LED.
- The HP 35 calculated arithmetic functions, logarithmic, and trigonometric, however, full implementation used only 767 carefully chosen instructions (7670 bits), in what is a marvel of concise programming.
- The introduction of the HP 35 scientific calculators and other similar capacity by Texas Instruments soon signaled the end of the slide rule as a status symbol among science and engineering students. The covers of the rules of calculations were disappearing to make way for the covers of the "electronic slide rule", and universities began to abandon the slide rule classes of their curriculum.
- The HP 35 was the beginning of a family of related calculators all sharing similar mechanical packaging:
- The screen was unique in the sense that multiplexing is designed to illuminate only one LED at a time segment, instead of a single-digit LED, because HP investigations had shown that this method was perceived by the human eye as more Bright energy equivalent.
- The calculator used three NiCd batteries "AA" assembled in a removable battery pack, owner of HP design. Battery packs and replacement are unavailable, leaving 35 HP depending existing alternating current, or the users must rebuild the battery pack using batteries themselves available. An external battery charger was available and could also function calculator from charger, with or without batteries installed.
Internally, the calculator was organized around a serial processor chipset (a bit) floating point number processing 56-bit, 14-digit numbers representing BCD.
It was introduced at a price of U.S. $ 395.1 and was available from January 4, 1972 to 1975. During that time over 300,000 units sold.
Before the HP 35, the only practical portable devices to perform trigonometric and exponential functions were slide rules. At that time, existing pocket calculators had only four functions, ie could only add, subtract, multiply and divide. Originally it had been known simply as "The Calculator", but Hewlett suggested that it should be called the HP 35 because it had 35 keys.
HP 35 was developed in two years, HP 35 was released in 1972.

What makes this calculator not common is the binary window.
First of all, as you can see the screen, each line of the stack contains 3 elements: decimal, hexadecimal and binary
So for instance, you can enter an hex number, “BF32” and then click on enter to put it in the stack. Each element is updated in real time.
If you want to enter it in binary format, Click on “Next”, and you have the functions for binary operations, then “BIN” button, “Prev” for previous keyboard and now the keyboard is only in binary mode/input.
Click on Next and you can perform binary operations, like for instance “OR” or “NOT”.
“Home” goes back to the main window. Then, you have the standard operators like “+”, “-“, “*” and “/” and also functions to manage the stack.
It is also possible to add comments which could be anything like for instance the unit of the result
The Logarithm Keyboard has all the standard “power” functions.
The Trigonometry Keyboard with true values of PI. For instance, Arc Sin of 1 has Pi/2 as a result. And if you need the value of ‘Pi/2’, just click on “value Pi” and the value in Degree gives 90. You can of course make the calculation in rad or degree.
I hope you will enjoy all the functionality of our high performing calculator.
