7.2.4 Floating Point Objects

PyFloatObject: This subtype of PyObject represents a Python floating point object.

PyTypeObject PyFloat_Type: This instance of PyTypeObject represents the Python floating point type. This is the same object as types.FloatType.

int PyFloat_Check( PyObject *p): Returns true if its argument is a PyFloatObject or a subtype of PyFloatObject. Changed in version 2.2: Allowed subtypes to be accepted.

int PyFloat_CheckExact( PyObject *p): Returns true if its argument is a PyFloatObject, but not a subtype of PyFloatObject. New in version 2.2.

PyObject* PyFloat_FromString( PyObject *str, char **pend): Creates a PyFloatObject object based on the string value in str, or NULL on failure. The pend argument is ignored. It remains only for backward compatibility.

PyObject* PyFloat_FromDouble( double v): Return value: New reference.
Creates a PyFloatObject object from v, or NULL on failure.

double PyFloat_AsDouble( PyObject *pyfloat): Returns a C double representation of the contents of pyfloat.

double PyFloat_AS_DOUBLE( PyObject *pyfloat): Returns a C double representation of the contents of pyfloat, but without error checking.
