SafeCast
The latest version of this topic can be found at SafeCast.
Casts one type of number to another type.
Syntax
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.
Return Value
true if no error occurs; false if an error occurs.
Remarks
This method is part of SafeInt Library and is designed for a single casting operation without creating an instance of the SafeInt Class.
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.
