Removed obsolete float_util.h as VS2013 supports standards well enough.

#include <cmath>. I asked you to self-review to find other instances of this.
The two I’ve called out aren’t the only ones that have been omitted in patch set
2. If you’re not going to take the time to find them, why should I?
