Re: [PrimeNumbers] Program to manipulate big numbers
- Primeform is the best "pocket calculator" for big numbers.
As a side effect it even tests for probable or proven primality too! :-)
It has many functions such as gcd, about the only useful thing that it
doesn't have is a modulo exponentiation :-( well it has it inside but you
can't use it from the UI )-:
I have recently found a new toy -
GNU Multiple Precision Arithmetic Library (GMP)
and I've heard good things about LiDIA which uses GMP,
linked amongst others from that web page.
