Norm

Description

Returns the length, or magnitude, of the specified vector.

FUNCTION Norm(Vec : VECTOR): REAL;
def vs.Norm(Vec):
    return REAL

Parameters

Name Type Description
Vec VECTOR Vector to be measured.

Remarks

(_c_, 2022.01.20) In Python the vector used as parameter MUST be 3-dimensional, or it will return gibberish. This doesn't matter in Pascal.

Examples

VectorScript

PROCEDURE Example;
VAR
    vec :VECTOR;
BEGIN
    vec.x := 1;
    vec.y := 1.732050807;
    Message(Norm(vec));
END;
RUN(Example);

PROCEDURE Example2;
VAR
    v1, v2 : VECTOR;
BEGIN
    v1.x := 12; v1.y := 1;
    v2.x := 3; v2.y := 15;
    Message( Norm(v1-v2) );
END;
Run(Example2);

Python

v1 = (12, 1, 0) # 3-dimensional tuple
v2 = (3, 15, 0)
vs.Message( str(vs.Norm( (v1[0] - v2[0], v1[1] - v2[1], v1[2] - v2[2]) )) )
BEGIN
	arm1 := startPt - centerPt;
	arm2 := endPt - centerPt;
	zeta := AngBVec(arm1, arm2);
	LenOfArc := (PI * Norm(arm1) * zeta)/ 180;
END;

end else BEGIN
	GetObjArrow( arrowLineH, style, size, Angle, bstart, bend );
	if bstart then GetSegPt2( arrowLineH, vec1[1], vec1[2] ) ELSE GetSegPt1( arrowLineH, vec1[1], vec1[2] );
END;
IF Abs( Norm( tempV - vec1 ) ) < Abs( Norm( originVec - vec1 ) ) THEN originVec := tempV;

h1 := OffsetPolygon(walls[cnt1], -1");
for cnt2 := GetVertNum(h1) downto 2 do BEGIN
	GetPolyPt(h1, cnt2 - 1, pt1.x, pt1.y);
	GetPolyPt(h1, cnt2,     pt2.x, pt2.y);
	IF Abs(Norm(pt2 - pt1)) < .0625" THEN DelVertex(h1, cnt2);
END;
import vs

# Returns the length, or magnitude, of the specified vector.
Vec = (0, 0)

value = vs.Norm(Vec)
vs.Message('Norm returned: ' + str(value))
