1950 * VarNumFromParseNum [OLEAUT32.47]
1951 *
1952 * Convert a NUMPARSE structure into a numeric Variant type.
1953 *
1954 * PARAMS
1955 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
1956 * rgbDig [I] Source for the numbers digits
1957 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
1958 * pVarDst [O] Destination for the converted Variant value.
1959 *
1960 * RETURNS
1961 * Success: S_OK. pVarDst contains the converted value.
1962 * Failure: E_INVALIDARG, if any parameter is invalid.
1963 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
1964 *
1965 * NOTES
1966 * - The smallest favoured type present in dwVtBits that can represent the
1967 * number in pNumprs without losing precision is used.
1968 * - Signed types are preferred over unsigned types of the same size.
1969 * - Preferred types in order are: integer, float, double, currency then decimal.
1970 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
1971 * for details of the rounding method.
1972 * - pVarDst is not cleared before the result is stored in it.
1973 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
1974 * design?): If some other VTBIT's for integers are specified together
1975 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
1976 * the number to the smallest requested integer truncating this way the
1977 * number. Wine doesn't implement this "feature" (yet?).

2727 * is not an EMPTY variant. All four VT_RESERVED combinations have a
2728 * different meaning:
2729 * - BSTR and other: BSTR is always greater than the other variant.
2730 * - BSTR|VT_RESERVED and other: a string comparison is performed.
2731 * - BSTR and other|VT_RESERVED: If the BSTR is a number a numeric
2732 * comparison will take place else the BSTR is always greater.
2733 * - BSTR|VT_RESERVED and other|VT_RESERVED: It seems that the other
2734 * variant is ignored and the return value depends only on the sign
2735 * of the BSTR if it is a number else the BSTR is always greater. A
