2021 * VarNumFromParseNum [OLEAUT32.47]
2022 *
2023 * Convert a NUMPARSE structure into a numeric Variant type.
2024 *
2025 * PARAMS
2026 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
2027 * rgbDig [I] Source for the numbers digits
2028 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
2029 * pVarDst [O] Destination for the converted Variant value.
2030 *
2031 * RETURNS
2032 * Success: S_OK. pVarDst contains the converted value.
2033 * Failure: E_INVALIDARG, if any parameter is invalid.
2034 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
2035 *
2036 * NOTES
2037 * - The smallest favoured type present in dwVtBits that can represent the
2038 * number in pNumprs without losing precision is used.
2039 * - Signed types are preferred over unsigned types of the same size.
2040 * - Preferred types in order are: integer, float, double, currency then decimal.
2041 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
2042 * for details of the rounding method.
2043 * - pVarDst is not cleared before the result is stored in it.
2044 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
2045 * design?): If some other VTBIT's for integers are specified together
2046 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
2047 * the number to the smallest requested integer truncating this way the
2048 * number. Wine doesn't implement this "feature" (yet?).

2802 * - BSTR and other|VT_RESERVED: If the BSTR is a number a numeric
2803 * comparison will take place else the BSTR is always greater.
2804 * - BSTR|VT_RESERVED and other|VT_RESERVED: It seems that the other
2805 * variant is ignored and the return value depends only on the sign
2806 * of the BSTR if it is a number else the BSTR is always greater. A
