|

| 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.
