Is there an equivalent to -ffast-math for a Visual Studio C ++ compiler

Question

I work with the default C ++ compiler (I assume it is called the Visual Studio C ++ compiler), which comes with Visual Studio 2013 with the flag /Ox( Full Optimization ). Due to floating point effects, I have to disable the flag -ffast-mathwhen using the compiler gcc. Is there an equivalent option for this flag in the Visual Studio C ++ compiler configuration?

You are looking /fp:precise, although this is also the default.
