/* LibTomMath, multiple-precision integer library -- Tom St Denis
* LibTomMath is library that provides for multiple-precision
* integer arithmetic as well as number theoretic functionality.
* The library is 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.
* Tom St Denis,,
#include <tommath.h>
/* determines the setup value */
void mp_dr_setup(mp_int *a, mp_digit *d)
/* the casts are required if DIGIT_BIT is one less than
* the number of bits in a mp_digit [e.g. DIGIT_BIT==31]
*d = (mp_digit)((((mp_word)1) << ((mp_word)DIGIT_BIT)) - ((mp_word)a->dp[0]));
