Make dir() wordier (see the new docstring). The new behavior is a mixed bag. It's clearly wrong for classic classes, at heart because a classic class doesn't have a __class__ attribute, and I'm unclear on whether that's feature or bug. I'll repair this once I find out (in the meantime, dir() applied to classic classes won't find the base classes, while dir() applied to a classic-class instance *will* find the base classes but not *their* base classes). Please give the new dir() a try and see whether you love it or hate it. The new dir([]) behavior is something I could come to love. Here's something to hate: >>> class C: ... pass ... >>> c = C() >>> dir(c) ['__doc__', '__module__'] >>> The idea that an instance has a __doc__ attribute is jarring (of course it's really c.__class__.__doc__ == C.__doc__; likewise for __module__). OTOH, the code already has too many special cases, and dir(x) doesn't have a compelling or clear purpose when x isn't a module.

	i = floor(x/y);
	f = x - i*y;
	if ((x < 0.0) != (y < 0.0))
		f = f-y;
	return f;
