PK
PyFloatObject
This subtype of PyObject represents a Python floating point object.
PyObject
PyFloat_Type
This instance of PyTypeObject represents the Python floating point type. This is the same object as float and types.FloatType.
PyTypeObject
float
types.FloatType
PyFloat_Check
Return true if its argument is a PyFloatObject or a subtype of PyFloatObject.
Changed in version 2.2: Allowed subtypes to be accepted.
PyFloat_CheckExact
Return true if its argument is a PyFloatObject, but not a subtype of PyFloatObject.
New in version 2.2.
PyFloat_FromString
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.
PyFloat_FromDouble
Create a PyFloatObject object from v, or NULL on failure.
PyFloat_AsDouble
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.

-1.0
PyErr_Occurred()
PyFloat_AS_DOUBLE
Return a C double representation of the contents of pyfloat, but without error checking.
PyFloat_GetInfo
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.
float.h
New in version 2.6.
PyFloat_GetMax
Return the maximum representable finite float DBL_MAX as C double.
PyFloat_GetMin
Return the minimum normalized positive float DBL_MIN as C double.
PyFloat_ClearFreeList
Clear the float free list. Return the number of items that could not be freed.
PyFloat_AsString
Convert the argument v to a string, using the same rules as str(). The length of buf should be at least 100.
str()
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.
PyObject_Str()
PyOS_double_to_string()
PyFloat_AsReprString
Same as PyFloat_AsString, except uses the same rules as repr(). The length of buf should be at least 100.
repr()
Deprecated since version 2.7: Use PyObject_Repr() or PyOS_double_to_string() instead.
PyObject_Repr()
