NAME

       BSON::Double - BSON type wrapper for Double

VERSION

       version v1.4.0

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, unless the value is 'Inf', '-Inf' or 'NaN' (which are illegal in JSON), in which case
       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.
