README
intx
High‑performance multiprecision integer library for C++
The intx header-only C++20 library provides allocation-free extended precision
integer types. They are implemented as arrays of std::uint64_t words
and closely match the behavior of built-in types.
Usage
To build, test or benchmark.
git clone https://github.com/chfast/intx
cd intx
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --parallel
