So i have to find its password and press a button or just find the password?

My solution is 1.52061 ¿Is it possible?. Sorry for my bad English ;)

Exactly 1.5206117639947453996940561267823061250557102935443782479396672938700617746736758676608778545506705188.

I hope don't be wrong ;)

Sorry but thats not right.
Think a bit outside the box...

Is it even analytically possible to find a correct input value? As the algorithm is so sensitive on smallest changes of the input value I am a bit lost here.

My solution "3231"
Right? :)

sorry, not right

My solution is "18975". The explaining document is still in the solutions pipeline. I was only able to bruteforce it because I ws hinted to an integer solution.

Solved too, but brute forced :( That was interesting in a sense that I discovered TI family of devices, never used before, but seen in shops :) was pretty fun playing around with emulator. Also found a website that can show source from application. Anyway, I couldn't write proper c# version of bruteforcer, turned out to be an issue of rounding difference of device and .net framework, so wrote it on device itself (and removed clock speed limit), took sometime and solution was found.

program code for device to bruteforce, mention that there will be a syntax error when solution is found, cause I didn't check documentation details on how to break out of the loop, just choose "quit" and answer will be there:

:While V < 1000000
:While C<100
:If A=19911.236
:Disp V
:Return 0;

Thank you!

Small addition: to fix syntax error please make sure to use "Return" without any arguments and semicolon (habit) :)
:Disp V

A decent emulator: TilEm

What would the inverse function be then?
I have tried:
