floor-div (clj)

function

(floor-div x y)

Integer division that rounds to negative infinity (as opposed to zero). The special case (floorDiv Long/MIN_VALUE -1) overflows and returns Long/MIN_VALUE. See: https://docs.oracle.com/javase/8/docs/api/java/lang/Math.html#floorDiv-long-long-

Examples

clojure

(ns clojure.test-clojure.math
  (:require
    [clojure.test :refer :all]
    [clojure.math :as m]))

(deftest test-floor-div
  (is (= Long/MIN_VALUE (m/floor-div Long/MIN_VALUE -1)))
  (is (= -1 (m/floor-div -2 5))))
