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,
