[New-bugs-announce] [issue37942] Generate correct error check for PyFloat_AsDouble

[Raymond Hettinger]

New submission from Raymond Hettinger <raymond.hettinger at gmail.com>:

The API for PyFloat_AsDouble() returns -1.0 to indicate an error.  PyErr_Occurred() should only be called if there is a -1.0 return code.  This is the normal practice for those calls and it is a bit faster because it avoids unnecessary external call.
