If interval is an interval with lower bounds $\ell_0,\dots,\ell_{d-1}$ and upper bounds $u_0,\dots,u_{d-1}$, and translation is a translation with entries $T_0,\dots,T_{d-1}$ , then interval-translate returns a new interval with lower bounds $\ell_0+T_0,\dots,\ell_{d-1}+T_{d-1}$ and upper bounds $u_0+T_0,\dots,u_{d-1}+T_{d-1}$. It is an error if the arguments do not satisfy these conditions.

One could define (interval-translate interval translation) by (interval-dilate interval translation translation).
