Description

In the Visual Studio 14 CTP, using C++, the float overload of the cos() function returns completely wrong results in x64 builds.

The bug appears in both Debug and Release builds.

This bug doesn't appear to affect 32-bit builds, nor does it affect the double-precision cos().

I've attached a demo project that repros the issue for me. Again, the issue only repros in the x64 build. I also included the built x64 Debug binaries so you can check them against yours.
