1976 * VarNumFromParseNum [OLEAUT32.47]
1977 *
1978 * Convert a NUMPARSE structure into a numeric Variant type.
1979 *
1980 * PARAMS
1981 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
1982 * rgbDig [I] Source for the numbers digits
1983 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
1984 * pVarDst [O] Destination for the converted Variant value.
1985 *
1986 * RETURNS
1987 * Success: S_OK. pVarDst contains the converted value.
1988 * Failure: E_INVALIDARG, if any parameter is invalid.
1989 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
1990 *
1991 * NOTES
1992 * - The smallest favoured type present in dwVtBits that can represent the
1993 * number in pNumprs without losing precision is used.
1994 * - Signed types are preferred over unsigned types of the same size.
1995 * - Preferred types in order are: integer, float, double, currency then decimal.
1996 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
1997 * for details of the rounding method.
1998 * - pVarDst is not cleared before the result is stored in it.
1999 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
2000 * design?): If some other VTBIT's for integers are specified together
2001 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
2002 * the number to the smallest requested integer truncating this way the
2003 * number. Wine doesn't implement this "feature" (yet?).

2743 *
2744 * NOTES
2745 * Native VarCmp up to and including WinXP doesn't like I1, UI2, VT_UI4,

2747 *
2748 * If both input variants are ERROR then VARCMP_EQ will be returned, else
2749 * an ERROR variant will trigger an error.
2750 *
2751 * Both input variants can have VT_RESERVED flag set which is ignored
2752 * unless one and only one of the variants is a BSTR and the other one
2753 * is not an EMPTY variant. All four VT_RESERVED combinations have a
2754 * different meaning:
2755 * - BSTR and other: BSTR is always greater than the other variant.
2756 * - BSTR|VT_RESERVED and other: a string comparison is performed.
2757 * - BSTR and other|VT_RESERVED: If the BSTR is a number a numeric
2758 * comparison will take place else the BSTR is always greater.
2759 * - BSTR|VT_RESERVED and other|VT_RESERVED: It seems that the other
2760 * variant is ignored and the return value depends only on the sign
2761 * of the BSTR if it is a number else the BSTR is always greater. A
2762 * positive BSTR is greater, a negative one is smaller than the other
