1980 * VarNumFromParseNum [OLEAUT32.47]
1981 *
1982 * Convert a NUMPARSE structure into a numeric Variant type.
1983 *
1984 * PARAMS
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.
1989 *
1990 * RETURNS
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.
1994 *
1995 * NOTES
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?).

2746 *
2747 * RETURNS
2748 * VARCMP_LT: left variant is less than right variant.
2749 * VARCMP_EQ: input variants are equal.
2750 * VARCMP_GT: left variant is greater than right variant.
2751 * VARCMP_NULL: either one of the input variants is NULL.
2752 * Failure: An HRESULT error code indicating the error.
2753 *
2754 * NOTES
2755 * Native VarCmp up to and including WinXP doesn't like I1, UI2, VT_UI4,

2757 *
2758 * If both input variants are ERROR then VARCMP_EQ will be returned, else
2759 * an ERROR variant will trigger an error.
2760 *
2761 * Both input variants can have VT_RESERVED flag set which is ignored
2762 * unless one and only one of the variants is a BSTR and the other one
2763 * is not an EMPTY variant. All four VT_RESERVED combinations have a
2764 * different meaning:
2765 * - BSTR and other: BSTR is always greater than the other variant.
2766 * - BSTR|VT_RESERVED and other: a string comparison is performed.
2767 * - BSTR and other|VT_RESERVED: If the BSTR is a number a numeric
2768 * comparison will take place else the BSTR is always greater.
2769 * - BSTR|VT_RESERVED and other|VT_RESERVED: It seems that the other
2770 * variant is ignored and the return value depends only on the sign
