On the other hand, I think (as you hint later) that it might be better just to not try to make the point formally in the PEP.
And it's a whole lot simpler to write...
if isclose(x, y):
...
instead of...
if y - y * 1e-8 <= x <= y + y * 1e-8:
...
I think the isclose() line is much easier to read!
And the function will probably get it right, where I may get one of the signs reversed, or make some other silly error in the expression.
So +1 from me.
Cheers, Ron
