Hey Jack,
I see your point – I’ll look into it when I have some time, but sounds like bigtime rounding errors.
What sort of app runs into this kind of trouble ???? :)
Thanks for the comment

nice function! I’ve used it in my application, and found a small bug with (almost) horizontal and vertical line segments:

where
A = (3.0999999999999996, 3.1499999999999995)
B = (5, 3.15)

E = (3.1499999999999995, 5.8500000000000005)
F = (3.1499999999999995, 3.0999999999999996)

and
ip = (3.1499999999999995, 3.149999999999999)

this line executes and returns null:
if ( ( A.y < B.y ) ? ip.y B.y : ip.y > A.y || ip.y A.y

Great!
You can’t know how useful it is to me! ;-)
