What will happen if calculations are not accurate for the X-, Y-, I-, and J-coordinates?

The Answer is Full-quadrant arcs are relatively easy to program without too many calculations. However, arcs that start or end at an odd angle may require the use of trigonometry to find the end points or the I- and J-values. We must be careful to make these calculations with a high degree of accuracy and not let rounding errors stack up. The calculations will need to be accurate to at least 0.001" for the X-, Y-, I-, and J-coordinates. Otherwise the machine will produce an error message telling us that the arc cannot be made with these values.
