I’m looking for a good and basic BigInt class in C++, I find a lot of implementation but most of the time, it’s complex implementation for crypto library…
By basic, I mean BigInt can deal with BigInt, long long and strings with operator overloading.
If I had time, I had done myself but I do not have time to create an entire BigInt class.
Here’s one. I haven’t used it, but it doesn’t look too complex, and it was the first result when I googled “bigint c++”.
