Faulty point seems to be Rectangle>>center. May be some other ones to find. But not sure what to do with it, should it lands on float and not integer?

Hello,

I have noted inaccuracy when drawing circle (seen screenshot with circle and tangent line intersecting circle in two points and not one). I looked at my code with possible rounding error related to a mix of float and integer, I pay attention to convert to float when needed, but I can't fix the situation. Can it be related to Athens ? Is it ok to feed Athens with float numbers ?

Thanks

Hilaire

Yes, Athens works with Floats. But not with Fractions I think Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. On Oct 8, 2014, at 4:43 PM, Hilaire <hilaire@drgeo.eu> wrote:

I guess so, but in my situation Rectangle attributes are already Float, so it does not change.

Anyway it improves the accuracy in my case to redefine this center method in my Morph context.

And it looks like Athens works with Float.
