BSON::Double - BSON type wrapper for Double
use BSON::Types ':all'; my $bytes = bson_double( $number );
This module provides a BSON type wrapper for a numeric value that would be represented in BSON as a double.
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.
Returns a double, unless the value is 'Inf', '-Inf' or 'NaN' (which are illegal in JSON), in which case an exception is thrown.
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:
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.
