Visual C++ Compiler Options 
/fp:[precise | except[-] | fast | strict ]

fast 
Creates the fastest code in the majority of cases. /fp:fast cannot be used with /fp:strict or /fp:precise, the last option specified on the command line will be used. /fp:fast and /fp:except will generate a compiler error. Selecting /Za (ANSI compatibility) and /fp:fast may result in unexpected behavior. For example, single-precision floating-point operations may not be rounded to single precision.
