Returns the value of a specified element of an array as a double value. If the specified element type is neither PVT_Integer nor PVT_Double, nDefValue is returned.
Syntax
HRESULT Arr_GetDouble([in] ULONG nIndex,
[in, defaultvalue(0.0)] double nDefValue,
[out, retval] double* nVal);
Parameters
- nIndex
- [in] Specifies the index of the array element.
- nDefValue
- [in, defaultvalue(0)] Default value that will be returned when specified index is out of range or the element is not a numeric value. If not specified, zero will be returned.
- nVal
- [out, retval] Pointer to the double variable that receives the returned value.
Return Value
Returns S_OK if operation was successful or error code in other cases. Returns S_FALSE when nDefValue returned.
