module BSON::Float
Injects behaviour for encoding and decoding floating point values to and from raw bytes as specified by the BSON
spec.
@see bsonspec.org/#/specification
@since 2.0.0
Constants
- BSON_TYPE
A floating point is type 0x01 in the
BSON
spec.@since 2.0.0
- PACK
The pack directive is for 8 byte floating points.

Public Instance Methods
Converts this object to a representation directly serializable to Extended JSON
(github.com/mongodb/specifications/blob/master/source/extended-json.rst).
This method returns the float itself if relaxed representation is requested and the value is finite, otherwise a $numberDouble hash.
@option opts [ nil | :relaxed | :legacy ] :mode Serialization mode
(default is canonical extended JSON)
@return [ Hash
| Float
] The extended json representation.
