* VarNumFromParseNum [OLEAUT32.47]
|
|
*
|
|
* 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 preferred 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.
|
|
* - WinXP and Win2003 support VTBIT_I8, VTBIT_UI8 but that's buggy (by
|
|
* design?): If some other VTBIT's for integers are specified together
|
|
* with VTBIT_I8 and the number will fit only in a VT_I8 Windows will "cast"
|
|
* the number to the smallest requested integer truncating this way the
|
|
* number. Wine doesn't implement this "feature" (yet?).

|

* RETURNS
|
|
* VARCMP_LT: left variant is less than right variant.
|
|
* VARCMP_EQ: input variants are equal.

* VARCMP_GT: left variant is greater than right variant.
|
|
* VARCMP_NULL: either one of the input variants is NULL.
|
|
* Failure: An HRESULT error code indicating the error.
|
|
*
|
|
* NOTES
|
|
* Native VarCmp up to and including WinXP doesn't like I1, UI2, VT_UI4,
|
|
* UI8 and UINT as input variants. INT is accepted only as left variant.
|
|
*
|
|
* If both input variants are ERROR then VARCMP_EQ will be returned, else
|
|
* an ERROR variant will trigger an error.
|
|
*
|
|
* Both input variants can have VT_RESERVED flag set which is ignored
|
|
* unless one and only one of the variants is a BSTR and the other one
|
|
* is not an EMPTY variant. All four VT_RESERVED combinations have a
|
|
* different meaning:
|
|
* - BSTR and other: BSTR is always greater than the other variant.
|
|
* - BSTR|VT_RESERVED and other: a string comparison is performed.
|
|
* - BSTR and other|VT_RESERVED: If the BSTR is a number a numeric
|
|
* comparison will take place else the BSTR is always greater.
|
|
* - BSTR|VT_RESERVED and other|VT_RESERVED: It seems that the other
|
|
* variant is ignored and the return value depends only on the sign
|
|
* of the BSTR if it is a number else the BSTR is always greater. A
|
|
* positive BSTR is greater, a negative one is smaller than the other
|
|
* variant.

|
* This only behaves like a boolean not operation if the value in

* before calling this function.
|
|
* - This function does not process by-reference variants.
|
