Why am I getting unexpected output when using floor with pow?

Question

So, I ran this code on my code blocks:

#include
#include
using namespace std;
int main()
{
    int a;
    a=pow(10,9);
    cout<&         


        

Answer 1

Actually, the maximum value for int is 2,147,483,647, therefore there should be no overflow or truncation (it's an int). And my output is exactly:

1000000000 1000000000 1000000000
