|
|
|
|
*
|
2003-08-05 01:24:44 +00:00
|
|
|
* LibTomMath is a library that provides multiple-precision
|
2003-02-28 16:08:34 +00:00
|
|
|
* integer arithmetic as well as number theoretic functionality.
|
|

|
*
|
2003-08-05 01:24:44 +00:00
|
|
|
* The library was designed directly after the MPI library by
|
2003-02-28 16:08:34 +00:00
|
|
|
* Michael Fromberger but has been written from scratch with
|
|
|
|
* additional optimizations in place.
