function Distance(const X1, Y1, X2, Y2: Integer): Extended;
Source Code
function Distance(const X1, Y1, X2, Y2: Integer): Extended; var A, B: Extended; begin A := X1 - X2; B := Y1 - Y2; Result := Sqrt(A * A + B * B); end;

- Before 3.21 the workaround for larger distances was not yet implemented.
- Bedore 3.37 returned an integer value
Description
Calculates the distance between 2 given points defined by (X1, Y1) and (X2, Y2).
