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"
