高精度的Java图形drawArc

I'm trying to draw a high precision arc in Java using AWT/Swing. The Graphics class offers the "drawArc" method to do this and in most cases this is fine. However, when the arc has a large radius (I.e. The "width" and "height" parameters are large) then the arc will not be drawn precisely. This is because the "startAngle" and "arcAngle" parameters are given as integer degrees. I'm forced to convert an angle (given in radians) to degrees and then rounding it. The loss of precision leads to the arc falling short of its actual end point (if you round down) or go further than it should (if you round up).I'm trying to draw a high precision arc in Java
