# BSON::Int32 - BSON type wrapper for Int32 - perldoc - [phpMan]

## NAME
    [BSON::Int32](https://www.chedong.com/phpMan.php/perldoc/BSON%3A%3AInt32/markdown) - BSON type wrapper for Int32

## VERSION
    version v1.12.2

## SYNOPSIS
        use [BSON::Types](https://www.chedong.com/phpMan.php/perldoc/BSON%3A%3ATypes/markdown) ':all';

        bson_int32( $number );

## 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.

## ATTRIBUTES
  value
    A numeric scalar. It will be coerced to an integer. The default is 0.

## METHODS
  TO_JSON
    Returns the value as an integer.

    If the "BSON_EXTJSON" environment variable is true and the "BSON_EXTJSON_RELAXED" environment
    variable is false, returns a hashref compatible with MongoDB's extended JSON
    <<https://github.com/mongodb/specifications/blob/master/source/extended-json.rst>> format, which
    represents it as a document as follows:

        {"$numberInt" : "42"}

## OVERLOADING
    The numification operator, "0+" is overloaded to return the "value", the full "minimal set" of
    overloaded operations is provided (per overload documentation) and fallback overloading is
    enabled.
