|---|
| 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. |
