BN_CMP(3)                           OpenSSL                          BN_CMP(3)
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.
