1887 *
1888 * Convert a NUMPARSE structure into a numeric Variant type.
1889 *
1890 * PARAMS
1891 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
1892 * rgbDig [I] Source for the numbers digits
1893 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
1894 * pVarDst [O] Destination for the converted Variant value.
1895 *
1896 * RETURNS
1897 * Success: S_OK. pVarDst contains the converted value.
1898 * Failure: E_INVALIDARG, if any parameter is invalid.
1899 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
1900 *
1901 * NOTES
1902 * - The smallest favoured type present in dwVtBits that can represent the
1903 * number in pNumprs without losing precision is used.
1904 * - Signed types are preferrred over unsigned types of the same size.
1905 * - Preferred types in order are: integer, float, double, currency then decimal.
1906 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
1907 * for details of the rounding method.
1908 * - pVarDst is not cleared before the result is stored in it.
