Create a PyFloatObject object based on the string value in str, or NULL on failure.
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.
Return a C double representation of the contents of pyfloat, but without error checking.
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.
Return the maximum representable finite float DBL_MAX as C double.
Return the minimum normalized positive float DBL_MIN as C double.
Clear the float free list. Return the number of items that could not be freed.
