Arb is an experimental C library implementing arbitrary-precision ball arithmetic, polynomials and matrices on top of FLINT (http://flintlib.org/). The project might get merged back into FLINT when the code stabilizes in the future. For documentation and additional details, see: http://fredrikj.net/arb/ Development updates are occasionally posted to: http://fredrikj.net/blog/ Author: Fredrik Johansson The build scripts are copied from FLINT and were written by Bill Hart.
