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.
This method returns -1.0 upon failure, so one should call
PyErr_Occurred() to check for errors.
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()
Return the maximum representable finite float DBL_MAX as C double.
New in version 2.6.
double PyFloat_GetMin()
Return the minimum normalized positive float DBL_MIN as C double.
New in version 2.6.
int PyFloat_ClearFreeList()
Clear the float free list. Return the number of items that could not be freed.
New in version 2.6.
void PyFloat_AsString(char *buf, PyFloatObject *v)
Convert the argument v to a string, using the same rules as
str(). The length of buf should be at least 100.
This function is unsafe to call because it writes to a buffer whose length it does not know.
Deprecated since version 2.7: Use PyObject_Str() or PyOS_double_to_string() instead.
void PyFloat_AsReprString(char *buf, PyFloatObject *v)
Same as PyFloat_AsString, except uses the same rules as
repr(). The length of buf should be at least 100.
This function is unsafe to call because it writes to a buffer whose length it does not know.
Deprecated since version 2.7: Use PyObject_Repr() or PyOS_double_to_string() instead.
