#if (vangle(vec2, chiral) > 0 | vangle (vec2, chiral) = 0)
vaxis_rotate(vecb, chiral, a2* 2* pi/circum)
else
vaxis_rotate(vecb, chiral, -a2* 2* pi/circum)

and i get
Parse Error: Expected 'numberic expression', undeclared identifier 'vangle'
found instead

And
So I tried declaring a variable
#declare vecra = (vangle(vec1, chiral));
but
Parse Error: Expected 'numberic expression', undeclared identifier 'vangle'
found instead

vangle is a function i can but....

and something about vangle..

let's say if i put vangle (v1,v2) = 60

then will vangle (v2,v1) = 300?
or -60?

Capitalization matters: try VAngle. (Or VAngleD if you're expecting degrees
instead of radians.)

No, they'll both return 60. In 3D space, the angle between two vectors is
always between 0 and 180.

Make sure that you included the file "math.inc" that contains the definitions 
for those macros.
Capitalisation DOES mather: vangle and VAngle are 2 distinct macro names.
VAngle(V1,V2) return the result as radiant.
VAngleD(V1,V2) return the result as degrees.
