NAME
    BSON::Double - BSON type wrapper for Double

VERSION
    version v1.12.2

SYNOPSIS
        use BSON::Types ':all';

        my $bytes = bson_double( $number );

DESCRIPTION
    This module provides a BSON type wrapper for a numeric value that would
    be represented in BSON as a double.

ATTRIBUTES
  value
    A numeric scalar (or the special strings "Inf", "-Inf" or "NaN"). This
    will be coerced to Perl's numeric type. The default is 0.0.

METHODS
  TO_JSON
    Returns a double.

    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-j
    son.rst> format, which represents it as a document as follows:

        {"$numberDouble" : "42.0"}

    If "BSON_EXTJSON" is false and the value is 'Inf', '-Inf' or 'NaN'
    (which are illegal in regular JSON), then an exception is thrown.

INFINITY AND NAN
    Some Perls may not support converting "Inf" or "NaN" strings to their
    double equivalent. They are available as functions from the POSIX
    module, but as a lighter alternative to POSIX, the following functions
    are available:

    *   BSON::Double::pInf() – positive infinity

    *   BSON::Double::nInf() – negative infinity

    *   BSON::Double::NaN() – not-a-number

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.
