=head1 NAME
BSON::Int32 - BSON type wrapper for Int32
=head1 VERSION
version v1.12.2
=head1 SYNOPSIS
use BSON::Types ':all';
bson_int32( $number );
=head1 DESCRIPTION
This module provides a BSON type wrapper for a numeric value that
would be represented in BSON as a 32-bit integer.
If the value won't fit in a 32-bit integer, an error will be thrown.
=head1 ATTRIBUTES
=head2 value
A numeric scalar. It will be coerced to an integer. The default is 0.
=head1 METHODS
=head2 TO_JSON
Returns the value as an integer.
If the C<BSON_EXTJSON> environment variable is true and the
C<BSON_EXTJSON_RELAXED> environment variable is false, returns a hashref
compatible with
MongoDB's L<extended JSON|https://github.com/mongodb/specifications/blob/master/source/extended-json.rst>
format, which represents it as a document as follows:
{"$numberInt" : "42"}
=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.
