The EXCEPT ALL

问题 I've written some code below to check if two line segments intersect and if they do to tell me where. As input I have the (x,y) coordinates of both ends of each line. It appeared to be working correctly but now in the scenario where line A (532.87,787.79)(486.34,769.85) and line B (490.89,764.018)(478.98,783.129) it says they intersect at (770.136, 487.08) when the lines don't intersect at all. Has anyone any idea what is incorrect in the below code? double dy[2], dx[2], m[2], b[2]; double
