I've been writing D bindings for GMP the multi-precision numeric
library. I know Dlang has bignum, but GMP is still the fastest
library for extremely large numbers.
I've thus far written header interface for all of gmp.h minus the
mpn_t functions (low level natural numbers). And I'm in the
process of implementing operations on a D struct that allow
manipulating mpn types as operations on operators.
If anybody has any idea about the process of getting such a
library accepted into the Demios repo, that would be greatly
appreciated.
