1986 * VarNumFromParseNum [OLEAUT32.47]
1987 *
1988 * Convert a NUMPARSE structure into a numeric Variant type.
1989 *
1990 * PARAMS
1991 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
1992 * rgbDig [I] Source for the numbers digits
1993 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
1994 * pVarDst [O] Destination for the converted Variant value.
1995 *
1996 * RETURNS
1997 * Success: S_OK. pVarDst contains the converted value.
1998 * Failure: E_INVALIDARG, if any parameter is invalid.
1999 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
2000 *
2001 * NOTES
2002 * - The smallest favoured type present in dwVtBits that can represent the
2003 * number in pNumprs without losing precision is used.
2004 * - Signed types are preferred over unsigned types of the same size.
2005 * - Preferred types in order are: integer, float, double, currency then decimal.
2006 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
2007 * for details of the rounding method.
2008 * - pVarDst is not cleared before the result is stored in it.
2009 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
2010 * design?): If some other VTBIT's for integers are specified together
2011 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
2012 * the number to the smallest requested integer truncating this way the
2013 * number. Wine doesn't implement this "feature" (yet?).
