Document Table of Contents The Convert Block and Real-world Values

The Convert block converts a data type to preserve the real-word value and optionally rounds and saturates the data type when not possible. Convert blocks can sign extend or discard bits as necessary. Similarly you can convert the same number of bits while preserving the real world value (as far as possible, subject to rounding and saturation).
