As close as you can get to an actual 15c without a physical keyboard. Even the dimensions are the same (Galaxy S4 Active) as my HP. For $10 it is worth it if RPN is your thing. The only change I can ask for is to make the font on the virtual keys bigger or bolder- they're tough to read especially with the screen brightness anything less than 100%. Great app otherwise!

Jim Gilbert

Good, except for display The calculator emulation is good, but the presentation and display is not as good as the Andro11c, which I also have installed (keys and display smaller, display not "Bolded"). A minor pox on HP for moving the pi key between the 11c and the 15c. I'm looking forward to installing it on my tablet, where the keys and display will be a little larger.

Eric Karnes

Works great. Works just like my old 15C. Obviously it's not as durable and doesn't have the tactile keys. But it's the next best thing to having my real HP 15c back. I owned three of them before moving up to the HP 32S and 48 GX.

Joseph Olson

As close as you'll get to the real thing I still use my HP15C, but when I don't have it on me this app is darn near like the real thing. The main difference is that there are no real buttons to push, but the haptic feedback is helpful in that regard. In addition, the size of the calculator display on my S4 is almost exactly the same size as the actual calculator. I just wish they would stop the pop up screen asking me to rate the app since I paid $10 for it!

A Google User

HP 15c Great app. Programmable, faster than the original. I love it. I hate algebraic calculators, always lose numbers and want to throw them away.

Walt Seefeld

Love this app! I wasn't a big 15c user, but I've always been a big 12c and 28x user. Seems the 15c is a great blend of the two. And this app makes it feel almost real. I haven't noticed any bugs or calculation flaws, so this is five stars for me.

User reviews

Wow. No complaints. Having lost my 11C a kajillion years ago, I was glad to see this. I'm also glad that it appears to actually work as advertised. I have to believe that the negative comments I've been reading apply to older versions, or different devices than mine (Samsung Galaxy 7.7). I can't find anything wrong. And everyone who knows me complains about how good I am at finding things wrong! (The real HP-15C doesn't have "online manuals." There's no reason for a simulation of it to have them. Yeah, having to take the tablet out of the keyboard dock so I can use it in "landscape mode" might not be convenient but that's the nature of the 15C and that family of HP calculators.)

Small problem with speed For technical reasons, the calculator cannot tell how long I press a key such as the (i) key, or the PREFIX key. The documentation says that the information will be flashed for a second, but (a) that is not always long enough to see all the digits, and (b) it is surely not long enough to see an entire complex part of a result computation. Worse, on my calculator, it doesn't flash anywhere near a second -- closer to 1/10th a second, making complex operations pretty useless.

f CLEAR Reg -- Not Working I just bought this and am surprised to discover within minutes of use that f CLEAR REG does not clear all the data registers as the original 15C was designed to do. If this isn't working and was discovered within minutes of use, what else isn't working? Poor quality control on coding. Unimpressed. Want my money back!

15C Great App Works very much like my old 15C did with one exception. I have been unable to set my display to a default of just 2 decimal points. I will use fix 2 and all is fine until I shut the app off; at which time it reverts back to the 4 decimal point default. Perhaps someone who knows how can pass it along to me. This is the only thing keeping me from a 5 rating. I will give it a 4.5.

Getting better! Works great but missing a few features. Key names are not displayed in a program mode.

Beautiful Emulator, Awesome Calculator My default calculator too! New graphics are a wonderful addition. Only gave It 4 stars because It needs a portrait mode with just the basic functions for quick use - Ie the numeric keys, basic math (+×÷-) enter swap roll etc. Also needs a cut/paste for the active contents so the user can provide numeric info from/to other apps without having to write it down.

Great program Works like my old calculator. I would recommend this one.

Great app I have been a long time user of the 15c. I personally own 5 of the original calculators. This is great !

## scientific calculator

NHN-1 is a free advanced engineering and scientific calculator with a transparent widget that has fractions and percentage:

•A resizeable widget with arithmetic, percentage button, and fractions.

•Expression (formula) based input.

•Fraction input and output with conversion to proper fraction, mixed fraction and decimal. Even the quadratic or cubic root functions, for instance, will return fractions when the answer can be written as a fraction.

•Full history with buttons that load old results, in case you need to start over from a previous point.

•Unlimited memory slots that can be named and are always displayed on screen.

•Multiple input fields except on small phones. This let's you do short side calculations without losing your place.

•Pre-packaged functions for quadratic equations as well as many geometric formulae.

•Buttons that store user defined functions that are created by binding an argument to a binary operator.

•Visualization of multivalued complex functions (roots, inverse trigonometric, logarithm)

•Visualization of quadratic and cubic functions

•Visualization of angles returned from inverse trigonometric functions.

•Complex numbers are very easy to work with, and all functions work with complex numbers where they are defined (inverse hyperbolic cosine, for instance).

•There is a fourth layout for small phones that is not shown in the screen shots.

•A unit conversion utility that lets you build arbitrary composite units. Conversion factors are written to the history, so you can bind the factor with multiplication to do the same conversion many times.

The layouts are designed to be ergonomic for each of four device sizes in portrait and landscape. Here are some examples of what we've done to make the calculator easy and speedy to work with:

•On small tablets in landscape, the keys are split so you can operate the calculator with two thumbs.

•On small phones, the numeric keypad is right under your thumb when holding the device with one hand.

•Square root, square, inverse and negation are all close to the numeric keypad.

•On small tablets, the long "NHN-1" button is a gesture recognizer that lets you scroll the six input fields with your left thumb. That way you don't have to let go of the device with your right hand to click an input field.

NOTE ABOUT INTERNET ACCESS: Calculator++ (version 1.2.24) contains advertisement which requires internet access. To get rid of it - purchase a version without ads (can be done from application's preferences).

FAQ

How can I get rid of the ads?

You can do it by purchasing the special option in the main application preferences.

Why Calculator++ needs INTERNET permission?

Currently application needs such permission only for one purpose - to show ads. If you buy the special option C++ will never use your internet connection.

How can I use functions written in the top right and bottom right corners of the button?

Push the button and slide lightly up or down. Depending on value showed on the button action will occur.

How can I toggle between radians and degrees?

To toggle between different angle units you can either change appropriate option in application settings or use the toggle switch located on the 6 button (current value is lighted with yellow color).

Also you can use deg() and rad() functions and ° operator to convert degrees to radians and vice versa.

Examples:

268° = 4.67748

30.21° = 0.52726

rad(30, 21, 0) = 0.52726

deg(4.67748) = 268

Does C++ support %?

Yes, % function can be found in the top right corner of / button.

Examples:

100 + 50% = 150

100 * 50% = 50

100 + 100 * 50% * 50% = 125

100 + (100 * 50% * (25 + 25)% + 100%) = 150

Note:

100 + (20 + 20)% = 140, but 100+ (20% + 20%) = 124.0

100 + 50% ^ 2 = 2600, but 100 + 50 ^ 2% = 101.08

Does C++ support fractional calculations?

Yes, you can type your fractional expression in the editor and use ≡ (in the top right corner of = button). Also you can use ≡ to simplify expression.

Examples:

2/3 + 5/9 ≡ 11/9

2/9 + 3/123 ≡ 91/369

(6-t) ^ 3 ≡ 216 - 108t + 18t ^ 2 - t ^ 3

Does C++ support complex calculations?

Yes, just enter complex expression (using i or √(-1) as imaginary number). ONLY IN RAD MODE!

Examples:

(2i + 1) ^ = -3 + 4i

e ^ i = 0.5403 + 0.84147i

Can C++ plot graph of the function?

Yes, type expression which contains 1 undefined variable (e.g. cos(t)) and click on the result. In the context menu choose 'Plot graph'.

Does C++ support matrix calculations?

No, it doesn't
