1971 * VarNumFromParseNum [OLEAUT32.47]
1972 *
1973 * Convert a NUMPARSE structure into a numeric Variant type.
1974 *
1975 * PARAMS
1976 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
1977 * rgbDig [I] Source for the numbers digits
1978 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
1979 * pVarDst [O] Destination for the converted Variant value.
1980 *
1981 * RETURNS
1982 * Success: S_OK. pVarDst contains the converted value.
1983 * Failure: E_INVALIDARG, if any parameter is invalid.
1984 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
1985 *
1986 * NOTES
1987 * - The smallest favoured type present in dwVtBits that can represent the
1988 * number in pNumprs without losing precision is used.
1989 * - Signed types are preferred over unsigned types of the same size.
1990 * - Preferred types in order are: integer, float, double, currency then decimal.
1991 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
1992 * for details of the rounding method.
1993 * - pVarDst is not cleared before the result is stored in it.
1994 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
1995 * design?): If some other VTBIT's for integers are specified together
1996 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
1997 * the number to the smallest requested integer truncating this way the
1998 * number. Wine doesn't implement this "feature" (yet?).

2738 *
2739 * NOTES
2740 * Native VarCmp up to and including WinXP doesn't like I1, UI2, VT_UI4,

2742 *
2743 * If both input variants are ERROR then VARCMP_EQ will be returned, else

2745 *
2746 * Both input variants can have VT_RESERVED flag set which is ignored
2747 * unless one and only one of the variants is a BSTR and the other one
2748 * is not an EMPTY variant. All four VT_RESERVED combinations have a
2749 * different meaning:
2750 * - BSTR and other: BSTR is always greater than the other variant.
2751 * - BSTR|VT_RESERVED and other: a string comparison is performed.
2752 * - BSTR and other|VT_RESERVED: If the BSTR is a number a numeric
2753 * comparison will take place else the BSTR is always greater.
2754 * - BSTR|VT_RESERVED and other|VT_RESERVED: It seems that the other
2755 * variant is ignored and the return value depends only on the sign
2756 * of the BSTR if it is a number else the BSTR is always greater. A
