| /Gf[+|-] | /Gf+ |
Use /Gf to specify fast floating-point execution.
If your program does not need to abide by ANSI rules regarding conversions of double and float types, you can use this option to increase your program's performance. Because the fast floating-point method does not perform all the conversions specified by the ANSI standards, the results obtained may differ from results obtained using ANSI methods, but are often more precise.
By default, the compiler takes advantage of fast floating-point execution.
