Can we all agree that vector / vector doesn''t make sense?
Depends on what kind of algebra you''re talking about. In geometric algebra, it''s all good.

We can simply define 1 / Vector as the reciprocal (say, Vector'') of that vector. Then Vector / Vector = Vector * Vector'' = Scalar.
Personnally, I''d use the ^ operator to represent what you call cross-product or whatever, and * for the scalar product.
As a side question, which one do you use most:
A.B = ||A|| * ||B|| * cos(A, B) or
A^B = k * ||A|| * ||B|| * sin(A, B)
(k being normal to the plane defined by A and B)
And C.x = A.x * B.x is what I would call "scaling a vector by a different along each axis"...

I do? Interesting interpretation...
Then, what are you doing here, except pointing out that my examples are *dumb*?

I think a component-wise division or multiplication would be useful in doing vector space conversion (i.e. ellipsoid collision detection)

Making matters worse, operators cannot always return error values, which might occur for example with matrix inversion.
What you want in that case is an exception .

AP, It''s blatently odvious you''ve never worked on a project with more than person, because otherwise you would value the importance of making operators clear and clean-cut.
One more person that has yet to learn how to read. Tragical, but I hope things work out for you nonetheless. And yes, I have worked on projects involving several people, even using such horrible things as xor operators denoting cross products and bitshift operators applied to streams. Really confusing stuff, don''t you think.
