What's the point of a binary search if the list is small enough to fit
on a line or two? And if a query can be substituted for N1-NN, you have
to read all the values anyway, and then the function is trivially
expressed as a normal query with no decrease in speed.

Here's an excerpt from the MySQL documentation:
INTERVAL(N,N1,N2,N3,...)
Returns 0 if N < N1, 1 if N < N2 and so on or -1 if N is
NULL. All arguments are treated as integers. It is required
that N1 < N2 < N3 < ... < Nn for this function to work
correctly. This is because a binary search is used (very fast).
