([[User:CBM-c-|_c_]], 2022.01.21) In Python, contrary to most Pascal-derived vectorial routines, it accepts also a bidimensional tuple without returning gibberish: the third item will always be ignored. So this is a 2D-only routine. | |||

Description
Returns TRUE if the 2D points are equal within the tolerance.
FUNCTION EqPt(
pt1 :VECTOR;
pt2 :VECTOR;
tolerance :REAL) : BOOLEAN;
def vs.EqPt(pt1, pt2, tolerance):
return BOOLEAN
Parameters
pt1 VECTOR pt2 VECTOR tolerance REAL
Remarks
(_c_, 2022.01.21) In Python, contrary to most Pascal-derived vectorial routines, it accepts also a bidimensional tuple without returning gibberish: the third item will always be ignored. So this is a 2D-only routine.
Example
PROCEDURE Example;
VAR
v1, v2 : VECTOR;
BEGIN
v1.x := 12; v1.y := 1; { z vals in 3-dimensional vectors will be ignored }
v2.x := 12; v2.y := 1;
Message(Concat( EqPt(v1, v2, 0) ));
END;
Run(Example);
v1 = (12, 1, 999) # z vals in 3-dimensional vectors will be ignored v2 = (12, 1, 0) vs.Message( str(vs.EqualPt(v1, v2, 0)) ) # surprisingly returns true in spite of the tuples being different, because the third item will be ignored.
