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. 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.
New in version 2.6.
- double PyFloat_GetMax(void)
Return the maximum representable finite float DBL_MAX as C double.
New in version 2.6.
- double PyFloat_GetMin(void)
Return the minimum normalized positive float DBL_MIN as C double.
New in version 2.6.
- int PyFloat_ClearFreeList(void)
Clear the float free list. Return the number of items that could not be freed.
New in version 2.6.
