Square root function not working

Superachar on

Соединенные Штаты

Not sure why, but the square root function doesn’t seem to be working properly now. Was working okay before. Not sure if other functions are also impacted. Used to love this up until this happened

Fantastic App!

I have always used HP RPN calculators spanning a period of over fifty years and this App is a faultless rendition of the original calculator. One really niggling problem is that the screen has rotated 90 degrees to landscape. Trying to get it back to portrate does not work. Any ideas? Any fix coming? Ray Shead

Thank you, thank you!!!

I’ve been using my hp42 since buying it the day it was in stock for sale. Its a one-owner! On back it says 1987 Made in USA. SERIAL No …A11141. I digress. Some of my keys have started to act up after 36 years of perfect service. Finding Free42 is a godsend! I’m running it on an iPhone SE. I re-entered some really old programs I’ve kept on my 42s and they work flawlessly. I am so grateful you’ve created this app. Thank you, thank you!

Love this calculator

I’ve been a fan of RPN for over 40 years. This calculator works great. I don’t typically use it for much more than simple calculations but I use it daily. I absolutely love the haptic feedback with key presses. It’s gives great indication when you’ve typed a number.

Great app

Terrific!

Needs shake to clear stack

Terrific, but will get 5 stars when it has the shake to clear stack that 42S had. But this app is 64 bit and 42S is out of the app store. Any chance of getting this great feature?

I’ve had a HPC 12 for years, and it was very simplistic to work with. This calculator is very complex and not easy to use. Does it even come with an instruction manual?

Loved HP calculators

Great RPN Calculator

I first started with my first RPN calculator when I worked in electrical engineering in the eighties with my HP15C. I used it very extensively, writing time saving programs for my job. (Also, the approximately $90 or so purchase price at the time, with a young family really hurt!) Although, my present position for the last twenty years doesn’t require anything advanced, RPN is still my first choice for a calculator. The “Free42” RPN calculator is easy to use & works well. I’m sorry to say that I haven’t used very many of the advanced functions. I have also loaded the windows version on my computer at work, with a skin that is similar to the HP15C (for sentimental reasons…). Also browsing the developer’s website, I was surprised to see that this software was created in 2004, has had many updates & is available for android, iPhone, Windows, Linux & Mac. Looking thru the updates listed on his website, this developer is very committed to this product. (it’s sad, my real HP15C calculator is just gathering dust in my dresser top junk drawer, half the time, the batteries die due to drainage from lack of use, it’s just too easy to reach for my iPhone that’s already in my pocket) My only complaint is the name. Free42 makes this product sound cheap & junky, it is not! Please consider a better name.

I feel so guilty.

I’ve been using Free 42 for years, I’ve never paid a penny! I paid for other HP emulators that I only sparingly used before deleting. At least add a menu item in ‘about’ that we can buy you a coffee!😊
