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