# 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` in the Python layer.

int `PyFloat_Check`(PyObject *p)
  Return true if its argument is a `PyFloatObject` or a subtype of `PyFloatObject`.

int `PyFloat_CheckExact`(PyObject *p)
  Return true if its argument is a `PyFloatObject`, but not a subtype of `PyFloatObject`.

PyObject* `PyFloat_FromString`(PyObject *str)
  Return value: New reference.

  Create a `PyFloatObject` object based on the string value in str, or NULL on failure.

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. If pyfloat is not a Python floating point object but has a `__float__()` method, this method will first be called to convert pyfloat into a float.

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

PyObject* `PyFloat_GetInfo`(void)
  Return a structseq instance which contains information about the precision, minimum and maximum values of a float. It’s a thin wrapper around the header file `float.h`.

double `PyFloat_GetMax`()
  Return the maximum representable finite float DBL_MAX as C `double`.

double `PyFloat_GetMin`()
  Return the minimum normalized positive float DBL_MIN as C `double`.

int `PyFloat_ClearFreeList`()
  Clear the float free list. Return the number of items that could not be freed.
