$-sqrt64=-8$ is an integer

As $64$ is a complete square, in fact it is $8^2$ i.e. square of a natural number / rational number, we have

$-sqrt64=-8$ , and it is

an integer, also a rational number $and may we say$ a real number.

But normally one describes it as the smallest set of number system to which it can be ascribed. Hence, we can say

$-sqrt64=-8$ is an integer

What is the set of numbers to which -sqrt64-sqrt64 belong?
