TVectorLength (Delphi)
Description
This example illustrates how to use the Length method to obtain the length of a vector.
Code
uses
System.SysUtils,
System.Types;
var
aVector: TVector;
aPoint: TPointF;
aLength: Single;
begin
aPoint.Create(2,3);
aVector.Create(aPoint);
writeln(Format('%2.2f %2.2f',[aVector.X,aVector.Y]));
// The console will output: 2.00 3.00, representing the coordinates for aVector.
aLength:=aVector.Length;
writeln(Format('%2.2f',[aLength]));
// The console will output: 3.61, representing the length of a aVector.
end.
