/QIfist

No compiler option is needed. The compiler has made significant improvements in float to int conversion speed.

Regarding rounding, /QIfist results in generation of the fistp instruction, which uses whatever ambient rounding mode is to do the conversion.

A routine to do this is:

int ftol_ambient(double d) {
   int i;
   __asm {
      fld d
      fistp i
   }
   return i;
}

/QIfist (Suppress _ftol)

/V

None

/V (Version Number)

/Yd

/Z7, /Zi, /ZI (Debug Information Format)

/Yd (Place Debug Information in Object File)

/Ze

None

/Za, /Ze (Disable Language Extensions)

/Zg

None
