They are much more efficient than the normal BIGNUM +arithmetic operations. + +BN_add_word() adds B<w> to B<a> (C<a+=w>). + +BN_sub_word() subtracts B<w> from B<a> (C<a-=w>). + +BN_mul_word() multiplies B<a> and B<w> (C<a*=w>). + +BN_div_word() divides B<a> by B<w> (C<a/=w>) and returns the remainder. + +BN_mod_word() returns the remainder of B<a> divided by B<w> (C<a%w>). + +For BN_div_word() and BN_mod_word(), B<w> must not be 0. + +=head1 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 L<ERR_get_error(3)>. + +BN_mod_word() and BN_div_word() return B<a>%B<w> on success and +B<(BN_ULONG)-1> if an error occurred. + +=head1 SEE ALSO + +L<bn(3)>, L<ERR_get_error(3)>, L<BN_add(3)> + +=head1 COPYRIGHT + +Copyright 2000-2016 The OpenSSL Project Authors.
