1920 * VarNumFromParseNum [OLEAUT32.47]
1921 *
1922 * Convert a NUMPARSE structure into a numeric Variant type.
1923 *
1924 * PARAMS
1925 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
1926 * rgbDig [I] Source for the numbers digits
1927 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
1928 * pVarDst [O] Destination for the converted Variant value.
1929 *
1930 * RETURNS
1931 * Success: S_OK. pVarDst contains the converted value.
1932 * Failure: E_INVALIDARG, if any parameter is invalid.
1933 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
1934 *
1935 * NOTES
1936 * - The smallest favoured type present in dwVtBits that can represent the
1937 * number in pNumprs without losing precision is used.
1938 * - Signed types are preferred over unsigned types of the same size.
1939 * - Preferred types in order are: integer, float, double, currency then decimal.
1940 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
1941 * for details of the rounding method.
1942 * - pVarDst is not cleared before the result is stored in it.
1943 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
1944 * design?): If some other VTBIT's for integers are specified together
1945 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
1946 * the number to the smallest requested integer truncating this way the
1947 * number. Wine doesn't implement this "feature" (yet?).

2698 * is not an EMPTY variant. All four VT_RESERVED combinations have a
2699 * different meaning:
2700 * - BSTR and other: BSTR is always greater than the other variant.
2701 * - BSTR|VT_RESERVED and other: a string comparison is performed.
2702 * - BSTR and other|VT_RESERVED: If the BSTR is a number a numeric
2703 * comparison will take place else the BSTR is always greater.
2704 * - BSTR|VT_RESERVED and other|VT_RESERVED: It seems that the other
2705 * variant is ignored and the return value depends only on the sign
