BSON::Double - BSON type wrapper for Double

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.

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

       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

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-json.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.

       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.

           use BSON::Types ':all';

           my $bytes = bson_double( $number );
