# _variant_t Extractors
**Microsoft Specific**  
  
 Extract data from the encapsulated **VARIANT** object.  
  
## Syntax  
  
```  
  
      operator short( ) const;   
operator long( ) const;   
operator float( ) const;   
operator double( ) const;   
operator CY( ) const;   
operator _bstr_t( ) const;   
operator IDispatch*( ) const;   
operator bool( ) const;   
operator IUnknown*( ) const;   
operator DECIMAL( ) const;   
operator BYTE( ) const;  
operator VARIANT() const throw();  
operator char() const;  
operator unsigned short() const;  
operator unsigned long() const;  
operator int() const;  
operator unsigned int() const;  
operator __int64() const;  
operator unsigned __int64() const;  
```  
  
## Remarks  
 Extracts raw data from an encapsulated **VARIANT**. If the **VARIANT** is not already the proper type, **VariantChangeType** is used to attempt a conversion, and an error is generated upon failure:  
  
-   **operator short( )** Extracts a **short** integer value.  
  
-   **operator long( )** Extracts a **long** integer value.  
  
-   **operator float( )** Extracts a **float** numerical value.  
  
-   **operator double( )** Extracts a **double** integer value.  
  
-   **operator CY( )** Extracts a **CY** object.  
  
-   **operator bool( )** Extracts a `bool` value.  
  
-   **operator DECIMAL( )** Extracts a **DECIMAL** value.  
  
-   **operator BYTE( )** Extracts a **BYTE** value.  
  
-   **operator _bstr_t( )** Extracts a string, which is encapsulated in a `_bstr_t` object.  
  
-   **operator IDispatch\*( )** Extracts a dispinterface pointer from an encapsulated **VARIANT**. `AddRef` is called on the resulting pointer, so it is up to you to call **Release** to free it.  
  
-   **operator IUnknown\*( )** Extracts a COM interface pointer from an encapsulated **VARIANT**. `AddRef` is called on the resulting pointer, so it is up to you to call **Release** to free it.
