/* LibTomPoly, Polynomial Basis Math -- Tom St Denis
|

|
|
*
|
||
|
|
* LibTomPoly is a public domain library that provides
|
||
|
|
* polynomial basis arithmetic support. It relies on
|
||
|
|
* LibTomMath for large integer support.
|
||
|
|
*
|
||
|
|
* This library is free for all purposes without any
|
||
|
|
* express guarantee that it works.
