Floating Point Objects
PyFloatObject-
This subtype of
PyObjectrepresents a Python floating point object.
- PyTypeObject
PyFloat_Type -
This instance of
PyTypeObjectrepresents the Python floating point type. This is the same object asfloatin the Python layer.
-
int
PyFloat_Check( PyObject *p ) -
Return true if its argument is a
PyFloatObjector a subtype ofPyFloatObject.
-
int
PyFloat_CheckExact( PyObject *p ) -
Return true if its argument is a
PyFloatObject, but not a subtype ofPyFloatObject.
- 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 callPyErr_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.
