If either X or Y value of each point differs, then False is returned.

Example code : Compare different and identical points | var
start, finish : TPoint;
begin
 // Set up the start and end points
start := Point(1, 2);
finish := Point(3, 4);
 // Is the start point equal to the finish point?
if PointsEqual(start, finish)
then ShowMessage('1,2 = 3,4')
else ShowMessage('1,2 <> 3,4');
 // Try using PointsEqual with identical values
if PointsEqual(Point(2,9), Point(2,9))
then ShowMessage('2,9 = 2,9')
else ShowMessage('2,9 <> 2,9');
end;
