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.
