1982 * Convert a NUMPARSE structure into a numeric Variant type.
1985 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
1986 * rgbDig [I] Source for the numbers digits
1987 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
1988 * pVarDst [O] Destination for the converted Variant value.
1991 * Success: S_OK. pVarDst contains the converted value.
1992 * Failure: E_INVALIDARG, if any parameter is invalid.
1993 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
1996 * - The smallest favoured type present in dwVtBits that can represent the
1997 * number in pNumprs without losing precision is used.
1998 * - Signed types are preferred over unsigned types of the same size.
1999 * - Preferred types in order are: integer, float, double, currency then decimal.
2000 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
2001 * for details of the rounding method.
2002 * - pVarDst is not cleared before the result is stored in it.
2003 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
2004 * design?): If some other VTBIT's for integers are specified together
2005 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
2006 * the number to the smallest requested integer truncating this way the
2007 * number. Wine doesn't implement this "feature" (yet?).
