2006 * VarNumFromParseNum [OLEAUT32.47]
2007 *
2008 * Convert a NUMPARSE structure into a numeric Variant type.
2009 *
2010 * PARAMS
2011 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
2012 * rgbDig [I] Source for the numbers digits
2013 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
2014 * pVarDst [O] Destination for the converted Variant value.
2015 *
2016 * RETURNS
2017 * Success: S_OK. pVarDst contains the converted value.
2018 * Failure: E_INVALIDARG, if any parameter is invalid.
2019 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
2020 *
2021 * NOTES
2022 * - The smallest favoured type present in dwVtBits that can represent the
2023 * number in pNumprs without losing precision is used.
2024 * - Signed types are preferred over unsigned types of the same size.
2025 * - Preferred types in order are: integer, float, double, currency then decimal.
2026 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
2027 * for details of the rounding method.
2028 * - pVarDst is not cleared before the result is stored in it.
2029 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
2030 * design?): If some other VTBIT's for integers are specified together
2031 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
2032 * the number to the smallest requested integer truncating this way the
2033 * number. Wine doesn't implement this "feature" (yet?).

2782 * unless one and only one of the variants is a BSTR and the other one
2783 * is not an EMPTY variant. All four VT_RESERVED combinations have a
2784 * different meaning:
2785 * - BSTR and other: BSTR is always greater than the other variant.
2786 * - BSTR|VT_RESERVED and other: a string comparison is performed.
2787 * - BSTR and other|VT_RESERVED: If the BSTR is a number a numeric
2788 * comparison will take place else the BSTR is always greater.
2789 * - BSTR|VT_RESERVED and other|VT_RESERVED: It seems that the other
2790 * variant is ignored and the return value depends only on the sign
2791 * of the BSTR if it is a number else the BSTR is always greater. A
