Austin Z. Henley Associate Teaching Professor Carnegie Mellon University 7/9/2024I'm down a rabbit hole of learning how bignums work. In the first post, making a bignum library for fun, I implemented a arbitrary-precision number library with some basic operations. You can follow along with the source on GitHub. int main() { BigNum a, b, sum; bignum_init(&a, "12345678901234567890"); bignum_init(&b, "98765432109876543210"); bignum_add(&sum, &a, &b); bignum_print(&sum); bignum_free(&a); bignum_free...
