1 /* LibTomMath, multiple-precision integer library -- Tom St Denis | |
2 * | |
3 * LibTomMath is a library that provides multiple-precision | |
4 * integer arithmetic as well as number theoretic functionality. | |
5 * | |
6 * The library was designed directly after the MPI library by | |
7 * Michael Fromberger but has been written from scratch with | |
8 * additional optimizations in place. | |
9 * | |
10 * The library is free for all purposes without any express | |
11 * guarantee it works. | |
