- interval-lower-bounds->vector intervalprocedure
- interval-upper-bounds->vector intervalprocedure
If interval is an interval built with
(make-interval lower-bounds upper-bounds)
then interval-lower-bounds->vector returns a copy of lower-bounds and interval-upper-bounds->vector returns a copy of upper-bounds. It is an error to call interval-lower-bounds->vector or interval-upper-bounds->vector if interval does not satisfy these conditions.
