        bool* ResultOverflowed = nullptr)

Description

Multiply two unsigned integers, X and Y, and add the unsigned integer, A to the product. Clamp the result to the maximum representable value of T on overflow. ResultOverflowed indicates if the result is larger than the maximum representable value of type T.
