15C Scientific Calculator by Vicinno

By Vicinno Soft LLC

This app is only available on the App Store for iOS devices.

Description

15C scientific calculator is a high-end scientific programmable calculator for iPhone and iPod touch, which behaves exactly like, and supports all functions of HP 15C Scientific Calculator.

"15C Scientific Calculator supports complex numbers, intense calculations, matrix operations, and many other features that I don't have room to list. " -- AppGratis.com

"This is a terrific emulation of the venerable HP-15C calculator -- the best one I've found in the App Store (and believe me, I've tried the others). Works just like the original, and it comes with a wealth of help functions -- pressing the Help button reveals the original User Manual and Advanced Functions Handbook in PDF format, as well as manuals for a number of other HP calculators. And it's always as close as your phone. " -- from app store review

"Does exactly what my HP15C does, and always with me in my pocket" -- David, Financial Analyst.

Built with identical mathematics and algorithms, it gives you same capabilities and better performance. It can perform numerical integration and solve the roots of equations in addition to supporting complex numbers and matrix calculations.

Works w/latest upgrade

I had been using a different 15c app, but this app-which I already had gotten, I suppose, DOES work with the latest upgrade. I am still getting accustomed to the ‘look.’ It’s a bit shiny-like a brand new HP15C-I can’t remember that far back can you? But I can’t calculate with any other system.
Mostly I have done simple math, but you can’t beat that back arrow key once you are deep into a stack. Speaking of which I have to give a shout out to my brilliant Principles of Finance professor. As we were working in class I said, “Where is the formula?” He said, “You don’t need the formula.” Our agreement had been that I could use my 15c (instead of the calc they suggested) as long as he didn’t have to help me put it into my calculator. All I said was, “I need to see the formula to put in the stack.” The man not only knew the exact page off of the top of his head, but since my 15 C would give ever so slightly different answers than the ‘suggested’ calculator, as he came around to me in the class he would tell me exactly what number I should have. He did all the math in his head while teaching the rest of the class. I couldn’t ask for a better business professor! I learned so much more from him than how to press people’s buttons. Go Cougars!

64-Bit Support?

This is my go to portable calculator, I own an old HP-45 & 15C but no battery for either so I relied on SCI-15c which was discontinued and went with Vicinno 15c which was updated for iPhone 6 screen. Used it a lot lately to modify a redesign analog FSK modem (along with Excel) and would be lost without it. I hope Vicinno plans to update to 64-bit for iOS 11 or I will have to buy HP app which will be the third time I have purchased. Thank you for keeping HP-15c alive!

Great emulator!

Try this on your calculator: (-.5!) then hit <Enter> or "=". The flashing display means the calculator is executing the wrong algorithm. It should evaluate to the sq. rt. of π. This app has the fine details that made the HP15C a classic. I knocked off one star just because the latest update tends to lock up the first time it's opened. Just restart.
