calculator -- 5

Allo, i need a Manual and Automatic calculator using java big integer; to calculate large numbers with thousands of digits.
The Look; see attached pic
Im using 64 bits windows 7 and not sure java 11 or 20
It will have Input1, Input2, Result, Number of Digits in Result, Add, Divide by 2, Reset

The Function;
I enter an odd number on Input1 and an odd number on Input2
When I click Add, the Result will show Input1 plus Input2
When I click Divide by 2, the Result will be divided by 2
And so on…
If I click Divide by 2 and the Result is not even, the calculator will not function
And Add will always function once a time

Example
1375 and 29 will be giving =1404=702=351=380=190=95=124=62=31=60=30=15 and so on…
At 1404 Number of Digits in Result will be 4, and so on…

Put copy and paste on every form

The Automatic Version
The Automatic will be the same as Manual the ONLY Difference is that instead of showing the Number of Digits in Result, I will be putting a number of Digits where the Calculator will STOP. For example if I put 2, the calculator will stop at 62

I usually pay 20 dollars for this type of calculator but this time I will pay around 27 dollars left on my account wishing you a Happy New Year 2024, you will show a Demo before I award you. Thank You
