BN_ADD_WORD(3)                      OpenSSL                     BN_ADD_WORD(3)
NAME
       BN_add_word, BN_sub_word, BN_mul_word, BN_div_word, BN_mod_word -
       arithmetic functions on BIGNUMs with integers
SYNOPSIS
        #include <openssl/bn.h>
        int BN_add_word(BIGNUM *a, BN_ULONG w);
        int BN_sub_word(BIGNUM *a, BN_ULONG w);
        int BN_mul_word(BIGNUM *a, BN_ULONG w);
        BN_ULONG BN_div_word(BIGNUM *a, BN_ULONG w);
        BN_ULONG BN_mod_word(const BIGNUM *a, BN_ULONG w);
DESCRIPTION
       These functions perform arithmetic operations on BIGNUMs with unsigned
       integers. They are much more efficient than the normal BIGNUM
       arithmetic operations.
       BN_add_word() adds w to a ("a+=w").
       BN_sub_word() subtracts w from a ("a-=w").
       BN_mul_word() multiplies a and w ("a*=w").
       BN_div_word() divides a by w ("a/=w") and returns the remainder.
       BN_mod_word() returns the remainder of a divided by w ("a%w").
       For BN_div_word() and BN_mod_word(), w must not be 0.
RETURN VALUES
       BN_add_word(), BN_sub_word() and BN_mul_word() return 1 for success, 0
       on error. The error codes can be obtained by ERR_get_error(3).
       BN_mod_word() and BN_div_word() return a%w on success and (BN_ULONG)-1
       if an error occurred.
