;; An exception to the docstring: (not= ##NaN ##NaN) ;; => false (not (= ##NaN ##NaN)) ;; => true ;; This is because of various shortcuts for checking identity when checking equality. ;; As a rule of thumb, don't rely on either for testing against the ##NaN literal. ;; Decide on which logic you want, and explicitly test. E.g. (defn != [x y] (or (not= x y) (NaN? x) (NaN? y))) (!= ##NaN ##NaN) ;; => true
