Casts one type of number to another type.

template<typename T, typename U>  
inline bool SafeCast (  
   const T From,  
   U& To  
);  

Parameters

[in] From
The source number to convert. This must be of type T.

[out] To
A reference to the new number type. This must be of type U.

true if no error occurs; false if an error occurs.

This method is part of SafeInt Library and is designed for a single casting operation without creating an instance of the SafeInt Class.

System_CAPS_ICON_note.jpg Note

This method should only be used when a single operation must be protected. If there are multiple operations, you should use the SafeInt class instead of calling the individual stand-alone functions.

For more information about the template types T and U, see SafeInt Functions.
