/* 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. * * Tom St Denis, [email protected], http://math.libtomcrypt.org */ #include <tommath.h> /* compare two ints (signed)*/ int mp_cmp (mp_int * a, mp_int * b) { /* compare based on sign */ if (a->sign != b->sign) { if (a->sign == MP_NEG) { return MP_LT; } else { return MP_GT; } } /* compare digits */ if (a->sign == MP_NEG) { /* if negative compare opposite direction */ return mp_cmp_mag(b, a); } else { return mp_cmp_mag(a, b); } }
