Nice. That's what I was looking for to improve my closest-note abstraction. See http://wiki.dataflow.ws/PdMtlAbstractions/Contents#head-musical It is currently only "flooring" the values, I think. Closest is what it really means to be. (with floats, not just integers.
If you need something that can work efficiently for a lot of intervals, what you ought to do is pre-sort them, then make a list of the averages of each two consecutive values. The result is a list of boundaries between the domains of each value; then you can find where is your closest value by a binary search in O(log n) time.
