List<Coordinate> coordinates = new ArrayList<Coordinate>();
coordinates.add(new Coordinate(194691.519, 325504.109));
coordinates.add(new Coordinate(194691.514, 325504.089));
coordinates.add(new Coordinate(194691.523, 325504.108));
Coordinate[] orderedCoordinates = coordinates.toArray(new Coordinate[coordinates.size()]);
        double tolerance = 0.001;
        Coordinate[] result = Circle.linearizeArc(
                orderedCoordinates[0].x, orderedCoordinates[0].y,
                orderedCoordinates[1].x, orderedCoordinates[1].y,
                orderedCoordinates[2].x, orderedCoordinates[2].y, tolerance);

When I set the value of the smallNumber variable in the method initThreePointCircle equal to the tolerance the function works.

Another thing I noticed in the initThreePointCircle method is the if statement after the declaration of the smallNumber variable:

if (       ( Math.abs( a13 ) < smallNumber && Math.abs( b13 ) < smallNumber )
				|| ( Math.abs( a13 ) < smallNumber && Math.abs( b13 ) < smallNumber )

it says if (a || a), where a is ( Math.abs( a13 ) < smallNumber && Math.abs( b13 ) < smallNumber ) should the second part be something else?
