SafeMultiply

Multiplies two numbers together in a way that protects against overflow.

template<typename T, typename U>
inline bool SafeMultiply (
   T t,
   U u,
   T& result
) throw ();

Parameters

  • [in] t
    The first number to multiply. This must be of type T.

  • [in] u
    The second number to multiply. This must be of type U.

  • [out] result
    The parameter where SafeMultiply stores the result.

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 multiplication operation without creating an instance of the SafeInt Class.

Nota

This method should only be used when a single mathematical 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.
