It depends upon how you define "small". It is the integer with the smallest absolute value, but there are an infinite number of (negative) integers less than zero. If "less than" means "smaller than", false is the answer.
I think also implied in the question is whether zero is an integer. Is it?
The opposite of zero is zero.
yes, zero is an integer
