[Pharo-users] inaccuracy in drawing?

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 -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu
