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

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.

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.

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.
MK-61 was the best seller of all USSR programmable calculators of 1980-s (B3-34, MK-54, MK-56, MK-61, MK-52).
Calculators are emulated on microcode level so they behave exactly like the original devices, including all non-documented features and inaccurate calculations. For ease of use application features saving and loading emulation states.
This app's emulation engine Java code is based on C++ source of Felix Lazarev's emu145 project.
Emulation was highly optimized for speed and should run in real time on any phone.
Hint 1: touch calculator's indicator to toggle slow/fast mode. Indicator's blinking looks better in slow mode.
Hint 2: you can choose between MK-61 and MK-54 using menu option that becomes visible when calculator is switched off.

IMPORTANT NOTE REGARDING LICENSE CHECK
For the license check, there is an network connection required. This license check is done only during program start and if there is a network connection present.
A valid license is cached in the app, so if no network connection is available (e.g. in Fligth-Mode or if you are traveling to a foreign country), the current license state is used and the app will start up even without a present network connection.
