When I was 21 years old, I had invented a postfix notation calculator that used the GMP library. At some point I lost all the code but my memory retains almost everything.
I have since written a similar calculator using native hardware integers. It is the chastdin calculator which has been written in C and Assembly for Intel and RISC-V.
It would not take much effort to fork the C version of the calculator and use the mpz_t integers from GMP to remake the calculator from 18 years ago.
Except this time it will probably be even better because I am far more advanced as a programmer compared to back then.
But this time, I don’t intend to lose it because now I have new ways of backing up data and publishing books of code with explanations.
Even when nobody else reads my books, I use them as reminders to myself of what I am doing and what I have learned.
There will be a math book I publish about Big Numbers or Arbitrary Precision Arithmetic. I haven’t figured out all the plans yet but it will finish the work I already started when I made my large powers of two programs and the factorial sequence.
