Py.FloatInterface for Python values of type Float.
val check : Object.t -> boolcheck o returns true if o is a Python float.
val of_float : float -> Object.tof_float f returns the Python long with the value f. Wrapper for PyFloat_AsDouble.
val to_float : Object.t -> floatto_float o returns the floating-point vale stored in o. A Python exception (Py.E _) is raised if o is not a float. Wrapper for PyFloat_FromDouble.
