Floating Point Objects¶
- 
PyTypeObject PyFloat_Type¶
- This instance of - PyTypeObjectrepresents the Python floating point type. This is the same object as- floatin the Python layer.
- 
int PyFloat_Check(PyObject *p)¶
- Return true if its argument is a - PyFloatObjector a subtype of- PyFloatObject. This function always succeeds.
- 
int PyFloat_CheckExact(PyObject *p)¶
- Return true if its argument is a - PyFloatObject, but not a subtype of- PyFloatObject. This function always succeeds.
- 
PyObject* PyFloat_FromString(PyObject *str)¶
- Return value: New reference.Create a PyFloatObjectobject based on the string value in str, orNULLon failure.
- 
PyObject* PyFloat_FromDouble(double v)¶
- Return value: New reference.Create a PyFloatObjectobject from v, orNULLon failure.
- 
double PyFloat_AsDouble(PyObject *pyfloat)¶
- Return a C - doublerepresentation 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. If- __float__()is not defined then it falls back to- __index__(). This method returns- -1.0upon failure, so one should call- PyErr_Occurred()to check for errors.- Changed in version 3.8: Use - __index__()if available.
- 
double PyFloat_AS_DOUBLE(PyObject *pyfloat)¶
- Return a C - doublerepresentation of the contents of pyfloat, but without error checking.
- 
PyObject* PyFloat_GetInfo(void)¶
- Return value: New reference.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.
