# With long doubles or a 32-bit integer perl, we're able to directly check
# if a value exceeds the maximum bounds of an int64_t. On a 64-bit Perl
# with only regular doubles, the loss of precision for doubles makes an
# exact check against the negative boundary impossible from pure-Perl.
# (The positive boundary isn't an issue because Perl will upgrade
# internally to uint64_t to do the comparision). Fortunately, we can take
# advantage of a quirk in pack(), where a float that is in the ambiguous
# negative zone or that is too negative to fit will get packed like the
# smallest negative int64_t.

=head1 NAME
BSON::Int64 - BSON type wrapper for Int64
=head1 VERSION
version v1.4.0
=head1 SYNOPSIS
use BSON::Types ':all';
bson_int64( $number );
=head1 DESCRIPTION
This module provides a BSON type wrapper for a numeric value that
would be represented in BSON as a 64-bit integer.
If the value won't fit in a 64-bit integer, an error will be thrown.
On a Perl without 64-bit integer support, the value must be a
L<Math::BigInt> object.
=head1 ATTRIBUTES
=head2 value
A numeric scalar. It will be coerced to an integer. The default is 0.
=head1 METHODS
=head2 TO_JSON
On a 64-bit perl, returns the value as an integer. On a 32-bit Perl, it
will be returned as a Math::BigInt object, which will
fail to serialize unless a C<TO_JSON> method is defined
for that or in package C<universal>.
If the C<BSON_EXTJSON> option is true, it will instead
be compatible with MongoDB's L<extended JSON|https://docs.mongodb.org/manual/reference/mongodb-extended-json/>
format, which represents it as a document as follows:
{"$numberLong" : "223372036854775807"}
=for Pod::Coverage BUILD
=head1 OVERLOADING
The numification operator, C<0+> is overloaded to return the C<value>,
the full "minimal set" of overloaded operations is provided (per L<overload>
documentation) and fallback overloading is enabled.
