I do not agree with you.
First of all the function works for zero argument,
namely leaving the argument unchanged.
Second, negation is subtraction from zero,
so when subtractions with negative result
throw an exception, negation of
non-zero values should also throw an exception.
That is how the mathematics is defined.
