1804 * VarNumFromParseNum [OLEAUT32.47]
1805 *
1806 * Convert a NUMPARSE structure into a numeric Variant type.
1807 *
1808 * PARAMS
1809 * pNumprs [I] Source for parsed number. cDig must be set to the size of rgbDig
1810 * rgbDig [I] Source for the numbers digits
1811 * dwVtBits [I] VTBIT_ flags from "oleauto.h" indicating the acceptable dest types
1812 * pVarDst [O] Destination for the converted Variant value.
1813 *
1814 * RETURNS
1815 * Success: S_OK. pVarDst contains the converted value.
1816 * Failure: E_INVALIDARG, if any parameter is invalid.
1817 * DISP_E_OVERFLOW, if the number is too big for the types set in dwVtBits.
1818 *
1819 * NOTES
1820 * - The smallest favoured type present in dwVtBits that can represent the
1821 * number in pNumprs without losing precision is used.
1822 * - Signed types are preferrred over unsigned types of the same size.
1823 * - Preferred types in order are: integer, float, double, currency then decimal.
1824 * - Rounding (dropping of decimal points) occurs without error. See VarI8FromR8()
1825 * for details of the rounding method.
1826 * - pVarDst is not cleared before the result is stored in it.
