Returns twice the signed area of the triangle a-b-c.

Returns true if a->b->c is a counterclockwise turn.

Compares two points by y-coordinate, breaking ties by x-coordinate. Formally, the invoking point (x0, y0) is less than the argument point (x1, y1) if and only if either y0 < y1 or if y0 = y1 and x0 < x1.

Returns the square of the Euclidean distance between this point and that point.

Returns the Euclidean distance between this point and that point.

Plot this point using standard draw.

Plot a line from this point to that point using standard draw.

Compares this point to the specified point.

Compares two points by atan2() angle (between -pi and pi) with respect to this point.

Compares two points by distance to this point.

Returns an integer hash code for this point.

Compares two points by polar angle (between 0 and 2pi) with respect to this point.

Demo test the point data type.

Return a string representation of this point.
