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.
