Visual Studio 2015 C++ Project Is Created With Errors

When I try to create a simple hello world in c++, I get around 500 errors, like these:

Error (active)      the global scope has no "float_t"   cTest   c:Program Files (x86)Microsoft Visual Studio 14.0VCincludecmath    679 13

using this code:

#include <iostream>

int main() {
std::cout << "hi";
return 0;
}

I have tried removing the other versions of visual studio on my computer, and all the files from the Program Files (x86), but that didn't help. I have also tried uninstalling and reinstalling, repairing, and installing and uninstalling Windows Kits, none of that worked. Anyone else having this problem, or knows how to solve it?
