NAME
     BN_cmp, BN_ucmp, BN_is_zero, BN_is_one, BN_is_word, BN_is_odd — BIGNUM
     comparison and test functions

SYNOPSIS
     #include <openssl/bn.h>

     int
     BN_cmp(BIGNUM *a, BIGNUM *b);

     int
     BN_ucmp(BIGNUM *a, BIGNUM *b);

     int
     BN_is_zero(BIGNUM *a);

     int
     BN_is_one(BIGNUM *a);

     int
     BN_is_word(BIGNUM *a, BN_ULONG w);

     int
     BN_is_odd(BIGNUM *a);

DESCRIPTION
     BN_cmp() compares the numbers a and b.  BN_ucmp() compares their absolute
     values.

     BN_is_zero(), BN_is_one() and BN_is_word() test if a equals 0, 1, or w
     respectively.  BN_is_odd() tests if a is odd.

     BN_is_zero(), BN_is_one(), BN_is_word(), and BN_is_odd() are macros.

RETURN VALUES
     BN_cmp() returns -1 if a<b, 0 if a==b, and 1 if a>b.  BN_ucmp() is the
     same using the absolute values of a and b.

     BN_is_zero(), BN_is_one(), BN_is_word(), and BN_is_odd() return 1 if the
     condition is true, 0 otherwise.

SEE ALSO

HISTORY
     BN_cmp(), BN_ucmp(), BN_is_zero(), BN_is_one() and BN_is_word() are
     available in all versions of SSLeay and OpenSSL.  BN_is_odd() was added
     in SSLeay 0.8.
