Great program, no instructions I am not talking instructions for using the TI-59, but instictions like installing modules, creating mag cards etc. A site for help and hints on using the App.

Love this but... I love this calculator and sincerely appreciate the effort that went in to it. It brings back lots of memories! This last update though doesn't fill my nexus 7 screen like the previous version did. I hope we can get that back. Thanks!

Nice Emulator. Very faithful to the original! Lawrence, if you're open to some simple suggestions, then consider breaking "true" emulation and make small concessions to the display. Back in the 70's the LED display technology was a huge limitation and some things that really should have been displayed were omitted. (1) A small status line to display things such as the current "2nd" and "INV" state, as well "Deg/Rad/Grad" would be incredibly useful. (2) In program mode a simple 3 character mnemonic (like "log" or "SUM" etc) could be appended to the numerical op-codes. This would greatly simplify program editing. Some purists might object to any departure from the original display, but it could be as an option.

Coolest app ever. This is NOT my favorite calculator. It IS my favorite app. (It's my 2nd favorite calc.) For a good calculator, and to answer everyone's reservations about this, get the "RealCalc" app. It does what you want. But THIS app, does even more. It's an almost perfect emulation of the Ti-58 programmable calculator. And that's what makes it so special. I can't believe how much work the author put into recreating this wondrous old machine. Here's my deal . . . I have to level some sophisticated avionics systems. I have an ultra-sensitive electronic level that reads out in tenths of a milliradian. I have to insert a shim that corrects for that deviation. So, I have a right-angle triangle with an adjacent of several inches, and an opposite of maybe .0005". Try plugging those numbers into any "triangle" app. Those apps are made for "high-school" shop class trigonomics. This app solved my problem. With a few simple "learning" key strokes, I entered a somewhat complex formula, and could convert a number that was tenths of a milliradian, directly to an appropriate shim size, with one "virtual button". The possibilities are infinite. I could write a book on how cool this app is. Perhaps I did.

Why not full screen? On my 7" Samsung tablet running 4.4, I'm getting a small image of the keyboard in the center of the screen with a large black border area all around. This app would be much easier to see and use if it was expanded to a full screen image.

I have put a link to the GitHub source repo in the store description, and it’s also in the about text in the app. There you will find tools for assembling programs from symbolic form and creating loadable program/library files. It's ok It's really good but how do I get to the integral and differential buttons? It's screen is small I expected to see a large screen to see steps to the answers too.

Lawrence D’Oliveiro March 28, 2014

Calculators in the 1970s didn’t have those functions. My Old Friend My TI58c got me through high school, trade school and college but it stopped working some years ago. I missed its simple but powerful programming and was pleasantly surprised to find this app. It's a really good recreation with modern conveniences. I use it every day. Good job and thank you!

nearly perfect! I love this calculator! It reminds me when I was a student (my math teacher had a ti58c, I couldn't afford it!). I'm wondering if also the other libraries will be implemented/completed sooner or later or not. PS: in the meantime I tried to add some modules to the orignal library, I started with ML-02 (DETERMINANT, MATRIx. & SIMUL EQ) as I found the source code. Unluckily the emulator could have a bug as it doesn't work.

Hmm Needs work. First thing I do on any calc is test divide by 0. Fail here, no error msg, just 0. Clicking key sounds are obnoxious and no apparent way to silence. On Nexus 7, app grabs whole screen and only uses 50%. At least make it float. All that in one minute test. There is promise here, but not ready for prime time. I'm shooting for the moon, not cosmic debris.

Great also. I still have my ti59 and the printer. The print head no longer works but it makes a good desk unit. I also have most of the ti59 newsletters (with all of tips and tricks). If you would like a copy of them let me know.

reminds me of my first TI-30 back in about 1979 03AUG2013 I love this APP. Reminds me of my first TI-30 which I think I got in High School around 1979. Doc Claridge (R.I.P.) our science teacher for two years, Physical Science and Chemistry, would not allow us to use calculators in class. We used slide rulers to calculate outputs of chemical reactions using quadratic equations as I recall.

Wonderful Loving this latest update to an already awesome calc. Easier to hit/see the buttons now.

Lawrence D’Oliveiro June 27, 2013

Not sure what you mean. Are the buttons unresponsive? A must for every android! If you ever had or used a ti58/59 before, this is a must. Even the faint "C" on the leftmost digit is faithfully implemented. Now with selectable key sound or vibrate or off. I wish there is a way to remove those posts with key sound complaints. This app would get a solid 5! I still own my real ti59. But this is faster and more accurate in calculations (of course). Wonderful, thank you! But wait ... all other modules please! :)

Keys are not responsive I push the keys and get locked out or they don't work at all. Galaxy SII

# What's New

15611.5: increase size of tappable button area to see if that reduces complaints about unresponsive buttons; more consistent layout size on larger vs smaller screens; notification status now appears while program is running in background, not just when it stops; CE in error state now clears error state without clearing display.

15457.0: scale layout on phone-sized screens while centring on tablet-sized screens.

If you find RealCalc useful, please consider purchasing RealCalc Plus to support further development. Thank you.

FAQ:

* If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see en.wikipedia.org/wiki/Kibibyte.

* If you can't find HEX, BIN or OCT modes, go to Menu > Settings and make sure that 'Radix Modes' is checked.

* If the percent key appears to give wrong answers, make sure you are pressing '=' at the end, e.g. '25 + 10 % =' will give 27.5.

* If sin/cos/tan functions don't give the answer you are expecting, make sure you are in the correct angle mode. Degrees, radians and grads are supported, indicated by DEG, RAD, GRAD in the display. Use the DRG key to change mode.

* If any of the digit keys are disabled, or the decimal point doesn't work, or you have answers with letters in, or basic arithmetic appears to be wrong, then you are in binary, octal or hexadecimal mode. Press DEC to return to decimal operation. If you don't need these modes, please make sure that 'Radix Modes' is disabled in the settings.

Infinirule is a virtual slide rule application for Android. It transcends the limitations of real physical slide rules by allowing variable precision--just keep zooming in to get more--and automatically wrapping scales around--like a circular slide rule, but without the bulk. And though it only shows four scales at a time, you can select any combination of the available scale types.
