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.
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.
