|
|
* NOTES
|
|
* This implements the low-level and hi-level APIs for manipulating VARIANTs.
|
|
* The low-level APIs are used to do data coercion between different data types.
|
|
* The hi-level APIs are built on top of these low-level APIs and handle
|
|
* initialization, copying, destroying and changing the type of VARIANTs.
|
|
*
|
|
* TODO:
|
|
* - The Variant APIs do not support international languages, currency
|
|
* types, number formating and calendar. They only support U.S. English format.
|
|
* - The Variant APIs do not the following types: IUknown, IDispatch, DECIMAL and SafeArray.
|
|
* - The parsing of date for the VarDateFromStr is not complete.
|
|
* - The date manipulations do not support dates prior to 1900.
|
|
* - The parsing does not accept as many formats as the Windows implementation.

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