1902 * Convert a NUMPARSE structure into a numeric Variant type.
1905 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
1906 * rgbDig [I] Source for the numbers digits
1907 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
1908 * pVarDst [O] Destination for the converted Variant value.
1911 * Success: S_OK. pVarDst contains the converted value.
1912 * Failure: E_INVALIDARG, if any parameter is invalid.
1913 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
1916 * - The smallest favoured type present in dwVtBits that can represent the
1917 * number in pNumprs without losing precision is used.
1918 * - Signed types are preferred over unsigned types of the same size.
1919 * - Preferred types in order are: integer, float, double, currency then decimal.
1920 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
1921 * for details of the rounding method.
1922 * - pVarDst is not cleared before the result is stored in it.
1923 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
1924 * design?): If some other VTBIT's for integers are specified together
1925 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
1926 * the number to the smallest requested integer truncating this way the
1927 * number. Wine doesn't implement this "feature" (yet?).
