1981 * VarNumFromParseNum [OLEAUT32.47]
1982 *
1983 * Convert a NUMPARSE structure into a numeric Variant type.
1984 *
1985 * PARAMS
1986 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
1987 * rgbDig [I] Source for the numbers digits
1988 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
1989 * pVarDst [O] Destination for the converted Variant value.
1990 *
1991 * RETURNS
1992 * Success: S_OK. pVarDst contains the converted value.
1993 * Failure: E_INVALIDARG, if any parameter is invalid.
1994 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
1995 *
1996 * NOTES
1997 * - The smallest favoured type present in dwVtBits that can represent the
1998 * number in pNumprs without losing precision is used.
1999 * - Signed types are preferred over unsigned types of the same size.
2000 * - Preferred types in order are: integer, float, double, currency then decimal.
2001 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
2002 * for details of the rounding method.
2003 * - pVarDst is not cleared before the result is stored in it.
2004 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
2005 * design?): If some other VTBIT's for integers are specified together
2006 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
2007 * the number to the smallest requested integer truncating this way the
2008 * number. Wine doesn't implement this "feature" (yet?).

2748 *
2749 * NOTES
2750 * Native VarCmp up to and including WinXP doesn't like I1, UI2, VT_UI4,

2752 *
2753 * If both input variants are ERROR then VARCMP_EQ will be returned, else

2755 *
2756 * Both input variants can have VT_RESERVED flag set which is ignored
2757 * unless one and only one of the variants is a BSTR and the other one
2758 * is not an EMPTY variant. All four VT_RESERVED combinations have a
2759 * different meaning:
2760 * - BSTR and other: BSTR is always greater than the other variant.
2761 * - BSTR|VT_RESERVED and other: a string comparison is performed.
2762 * - BSTR and other|VT_RESERVED: If the BSTR is a number a numeric
2763 * comparison will take place else the BSTR is always greater.
2764 * - BSTR|VT_RESERVED and other|VT_RESERVED: It seems that the other
2765 * variant is ignored and the return value depends only on the sign
2766 * of the BSTR if it is a number else the BSTR is always greater. A
