union is default public accessible
destruction is reverse of construction

void foo(float x, float y)
{
    int p = (int) x;
    int * p1 = reinterpret_cast<int*>(&x);
    int * p2 = reinterpret_cast<int*>(&y);
    std::cout<<(*p1<*p2)==(x,y)<<std::endl; //THIS ALWAYS HOLDS because FPU checks are always the same as integer checks
    //However this entire thing breaks if it's an unsigned int.
