clojure.math.numeric-tower
========================================
Formerly clojure.contrib.math
Math functions that deal intelligently with the various
types in Clojure's numeric tower, as well as math functions
commonly found in Scheme implementations.
Functions included:
* (expt x y) - x to the yth power
* (abs n) - absolute value of n
* (gcd m n) - greatest common divisor of m and n
* (lcm m n) - least common multiple of m and n
* (floor x) - round down
* (ceil x) - round up
* (round x) - round to nearest
* (sqrt x) - square root, exact if possible
* (exact-integer-sqrt k) returns floor of square root and the "remainder"
More documentation in docstrings.

[a b]
(reduce + (map (comp sqr -) a b)))
