[PD] match the closest number

[Mathieu Bouchard]

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.
