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 float and types.FloatType.

int PyFloat_Check(

PyObject *p)

Return 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)

Return 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)

Return value: New reference.

Create 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.

Create a PyFloatObject object from v, or NULL on failure.

double PyFloat_AsDouble(

PyObject *pyfloat)

Return a C double representation of the contents of pyfloat.

double PyFloat_AS_DOUBLE(

PyObject *pyfloat)

Return a C double representation of the contents of pyfloat, but without error checking.
