NAME ^

BSON::Double - BSON type wrapper for Double

VERSION ^

version v1.6.4

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:

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.
