[Moose-dev] Roassal Grapher problem

For some function, the Roassal Grapher is not really good. Try this for example:

b := RTGrapher new. b extent: 600 @ 200. ds := RTDataSet new. ds dotShape ellipse size: 0. ds points: (-2.0 to: 10.0 by: 0.001). ds connectColor: Color red. ds x: #yourself. ds y: [ :x | (x exp) sin ]. b add: ds. b axisXWithNumberOfTicks: 3. b axisYWithNumberOfTicks: 4. b build. b view

This is well known problem when someone use n-equally space joint in a grapher. There is some explanation here: http://maurizzzio.github.io/function-plot/

The solution need to implement an interval arithmetic library apparently. Nicolas implement an arbitrary-precision float library available in SciSmalltalk, but I not sure this is enough for a grapher.
