=head1 DESCRIPTION
B<BN_ULONG> is a macro that will be an unsigned integral type optimied
for the most efficient implementation on the local platform.
BN_zero(), BN_one() and BN_set_word() set B<a> to the values 0, 1 and
B<w> respectively. BN_zero() and BN_one() are macros.
BN_value_one() returns a B<BIGNUM> constant of value 1. This constant
is useful for use in comparisons and assignment.
BN_get_word() returns B<a>, if it can be represented as an unsigned
long.
BN_get_word() returns B<a>, if it can be represented as a B<BN_ULONG>.
=head1 RETURN VALUES
BN_get_word() returns the value B<a>, and 0xffffffffL if B<a> cannot
be represented as an unsigned long.
BN_get_word() returns the value B<a>, or all-bits-set if B<a> cannot
be represented as a B<BN_ULONG>.
BN_zero(), BN_one() and BN_set_word() return 1 on success, 0 otherwise.
BN_value_one() returns the constant.
=head1 BUGS
Someone might change the constant.
If a B<BIGNUM> is equal to the value of all-bits-set, it will collide
with the error condition returned by BN_get_word() which uses that
as an error value.
If a B<BIGNUM> is equal to 0xffffffffL it can be represented as an
unsigned long but this value is also returned on error.
B<BN_ULONG> should probably be a typedef.
