The instant constructor point() creates a point operand dynamically. Point operands store a 2D point value composed of the X and Y coordinate.

The first version of the point() constructor returns a point value with the X and Y point coordinates initialized with the values passed in the both parameters aX and aY. For example:

The second version of the point() constructor doesn't accept any arguments. It simply returns a point value with its X and Y coordinates set to 0 (zero). The function of this constructor corresponds thus to the point literal <0,0>.
