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