Description

Methods

	`function Ceiling: TPoint;`
Rounds the coordinates of the point to the nearest integer towards positive infinity

	`function Floor: TPoint;`
Rounds the coordinates of the point to the nearest integer towards negative infinity

	`function IsEmpty: boolean;`
Determines if the point is empty (has special coordinates EmptyPointF)

	`function Length: Single;`
Calculates the `length` (magnitude) of the point from the origin

	`function Round: TPoint;`
Rounds the coordinates of the point to the nearest integer

	`function Truncate: TPoint;`
Truncates the coordinates of the point, discarding fractional part

	`procedure Normalize;`
Normalizes the point (modifies it to a unit length)

	`procedure Offset(const apt: TPoint); overload;`
Offsets the point by another point (TPoint)

	`procedure Offset(const apt: TPointF); overload;`
Offsets the point by another point (TPointF)

	`procedure Offset(dx, dy: longint); overload;`
Offsets the point by specified distances in the X (dx) and Y (dy) directions (integer values)

	`procedure Offset(dx, dy: single); overload;`
Offsets the point by specified distances in the X (dx) and Y (dy) directions (single values)

	`procedure Scale(AScale: single);`
Scales the point as a vector from the origin) by a specified factor
