user> (- 0 -9223372036854775808) -9223372036854775808 It's worth noting that -9223372036854775808 is Long/MIN_VALUE, and that this is the expected result with native 64-bit longs, though not in a language with automatic long-to-BigInteger conversion. It appears that a few related bugs (e.g.: http://dev.clojure.org/jira/browse/CLJ-32) have been caught and fixed, but this one still lives.
