(unchecked-negate x)

Answers minus x of integers wrapped to 64 bits, so (unchecked-negate -9223372036854775808) is -9223372036854775808. A double or a ratio takes the plain result. nil and non-numbers signal. As a value a one-argument function.

An integer past 64 bits is a plain integer here, so the oracle's unwrapped bigint (100000000000000000000N) wraps too.
