2052 * VarNumFromParseNum [OLEAUT32.47]
2053 *
2054 * Convert a NUMPARSE structure into a numeric Variant type.
2055 *
2056 * PARAMS
2057 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
2058 * rgbDig [I] Source for the numbers digits
2059 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
2060 * pVarDst [O] Destination for the converted Variant value.
2061 *
2062 * RETURNS
2063 * Success: S_OK. pVarDst contains the converted value.
2064 * Failure: E_INVALIDARG, if any parameter is invalid.
2065 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
2066 *
2067 * NOTES
2068 * - The smallest favoured type present in dwVtBits that can represent the
2069 * number in pNumprs without losing precision is used.
2070 * - Signed types are preferred over unsigned types of the same size.
2071 * - Preferred types in order are: integer, float, double, currency then decimal.
2072 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
2073 * for details of the rounding method.
2074 * - pVarDst is not cleared before the result is stored in it.
2075 * - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
2076 * design?): If some other VTBIT's for integers are specified together
2077 * with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
2078 * the number to the smallest requested integer truncating this way the
2079 * number. Wine doesn't implement this "feature" (yet?).

2801 * VarCmp [OLEAUT32.176]
2802 *
2803 * Compare two variants.
2804 *
2805 * PARAMS
2806 * left [I] First variant
2807 * right [I] Second variant
2808 * lcid [I] LCID (locale identifier) for the comparison
2809 * flags [I] Flags to be used in the comparison:
2810 * NORM_IGNORECASE, NORM_IGNORENONSPACE, NORM_IGNORESYMBOLS,
2811 * NORM_IGNOREWIDTH, NORM_IGNOREKANATYPE, NORM_IGNOREKASHIDA
2812 *
2813 * RETURNS
2814 * VARCMP_LT: left variant is less than right variant.
2815 * VARCMP_EQ: input variants are equal.
2816 * VARCMP_GT: left variant is greater than right variant.
2817 * VARCMP_NULL: either one of the input variants is NULL.
2818 * Failure: An HRESULT error code indicating the error.
2819 *
2820 * NOTES
2821 * Native VarCmp up to and including WinXP doesn't like I1, UI2, VT_UI4,
2822 * UI8 and UINT as input variants. INT is accepted only as left variant.
2823 *
2824 * If both input variants are ERROR then VARCMP_EQ will be returned, else
2825 * an ERROR variant will trigger an error.
2826 *
2827 * Both input variants can have VT_RESERVED flag set which is ignored
2828 * unless one and only one of the variants is a BSTR and the other one
2829 * is not an EMPTY variant. All four VT_RESERVED combinations have a
2830 * different meaning:
2831 * - BSTR and other: BSTR is always greater than the other variant.
2832 * - BSTR|VT_RESERVED and other: a string comparison is performed.
2833 * - BSTR and other|VT_RESERVED: If the BSTR is a number a numeric
2834 * comparison will take place else the BSTR is always greater.
2835 * - BSTR|VT_RESERVED and other|VT_RESERVED: It seems that the other
2836 * variant is ignored and the return value depends only on the sign
2837 * of the BSTR if it is a number else the BSTR is always greater. A
2838 * positive BSTR is greater, a negative one is smaller than the other
2839 * variant.
2840 *
2841 * SEE
2842 * VarBstrCmp for the lcid and flags usage.
