Is there a technical term for a cube where each edge is 2 units? If so what is the term?

Question

I frequently work with code where I sample from a 3D cube bounded by -1,-1,-1 to 1,1,1 centred at 0,0,0.

It would be handy to know if it has a technical name, so my code can be consistent with mathematical convention.

Which leads to my question, is there a technical term for a cube where each edge is 2 units? If so what is the term?

Answer 1

This is the unit ball for the maximum metric (or norm), a special case of an $\ell_p$ norm for $p=\infty$.
